gitweb: Add support for hash_parent_base parameter for blobdiffs
Add support for hash_parent_base in input validation part and in
href() function. Add proper hash_parent_base to all calls to blobdiff
and blobdiff_plain action URLs. Use hash_parent_base as hash_base for
blobs of hash_parent.
To be used in future rewrite of git_blobdiff and git_blobdiff_plain.
While at it, move project before action in ordering CGI parameters in
href().

Adds git_get_following_references function, based on code which was
used in git_commitdiff_plain to generate X-Git-Tag: header,
and companion git_get_preceding_references function.
Both functions return array of all references of given type (as
returned by git_get_references) following/preceding given commit in
array (list) context, and last following/first preceding ref in scalar
context.
Stripping ref (list of refs) of "$type/" (e.g. "tags/") is left to
caller.

Change output of patch(set) in git_commitdiff from slurping whole diff
in @patchset array before processing, to passing file descriptor to
git_patchset_body.
Advantages: faster, incremental output, smaller memory footprint.
Disadvantages: cannot react when there is error during closing file
descriptor.

gitweb: Use git-diff-tree patch output for commitdiff
Get rid of git_diff_print invocation in git_commitdiff and therefore
external diff (/usr/bin/diff) invocation, and use only git-diff-tree
to generate patch.
git_commitdiff and git_commitdiff_plain are collapsed into one
subroutine git_commitdiff, with format (currently 'html' which is
default format corresponding to git_commitdiff, and 'plain'
corresponding to git_commitdiff_plain) specified in argument.
Separate patch (diff) pretty-printing into git_patchset_body.
It is used in git_commitdiff.
Separate patch (diff) line formatting from git_diff_print into
format_diff_line function. It is used in git_patchset_body.
While at it, add $hash parameter to git_difftree_body, according to
rule that inner functions should use parameter passing, and not global
variables.
CHANGES TO OUTPUT:
* "commitdiff" now products patches with renaming and copying
detection (git-diff-tree is invoked with -M and -C options).
Empty patches (mode changes and pure renames and copying)
are not written currently. Former version broke renaming and
copying, and didn't notice mode changes, like this version.
* "commitdiff" output is now divided into several div elements
of class "log", "patchset" and "patch".
* "commitdiff_plain" now only generates X-Git-Tag: line only if there
is tag pointing to the current commit. Former version which wrote
first tag following current commit was broken[*1*]; besides we are
interested rather in tags _preceding_ the commit, and _heads_
following the commit. X-Git-Url: now is current URL; former version
tried[*2*] to output URL to HTML version of commitdiff.
* "commitdiff_plain" is generated by git-diff-tree, and has therefore
has git specific extensions to diff format: "git diff" header and
optional extended header lines.
FOOTNOTES
[*1*] First it generated rev-list starting from HEAD even if hash_base
parameter was set, second it wasn't corrected according to changes
made in git_get_references (formerly read_info_ref) output, third even
for older version of read_info_ref output it didn't work for multiple
tags pointing to the current commit (rare).
[*2*] It wrote URL for commitdiff without hash_parent, which produces
diff to first parent and is not the same as current diff if it is diff
of merge commit to non-first parent.

gitweb: Route rest of action subroutines through %actions
Route rest of action subroutines, namely git_project_list and git_opml
(both of which doesn't need $project) through %actions hash.
This has disadvantage that all parameters are read and validated;
earlier git_opml was called as soon as $action was parsed and
validated, git_project_list was called as soon as $project was parsed
and validated. This has advantage that all action dispatch is grouped
in one place.

"a.list" being "bold", makes a myriad of things shown by
gitweb in bold font-weight, which is a regression from
pre-17d07443188909ef5f8b8c24043cb6d9fef51bca behavior.
The fix is to add "subject" class and use this class
to replace pre-format_subject_html formatting of subject
(comment) via using (or not) <b>...</b> element. This
should go back to the pre-17d0744318... style.

finish_connect(): thinkofix

Solaris does not support C99 format strings before version 10
All but one callers have ignore the return value from this
function, but the only caller, builtin-tar-tree.c::remote_tar(),
assumed it returns non-zero on failure and zero on success. The
implementation however was returning either the waited pid
(which must be the same as its input) or -1 (an error).
Fix this thinko, while getting rid of an assignment of return
value from waitpid() into a variable of type int.
On Solaris nanosleep(2) is not available in libc; you need to
link with -lrt to get it.
The purpose of the loop is to wait until the next filesystem
timestamp granularity, and the code uses subsecond sleep in the
hope that it can shorten the delay to 0.5 seconds on average
instead of a full second. It is probably not worth depending on
an extra library for this.
We might want to yank out the whole "racy-git avoidance is
costly later at runtime, so let's delay writing the index out"
codepath later, but that is a separate issue and needs some
testing on large trees to figure it out. After playing with the
kernel tree, I have a feeling that the whole thing may not be
worth it.
git-apply --binary: clean up and prepare for --reverse
This cleans up the implementation of "git-apply --binary", and
implements reverse application of binary patches (when git-diff
is converted to emit reversible binary patches).
Earlier, the types of encoding (either deflated literal or
deflated delta) were stored in is_binary field in struct patch,
which meant that we cannot store more than one fragment that
differ in the encoding for a patch. This moves the information
to a field in struct fragment that is otherwise unused for
binary patches, and makes it possible to hang two (or more, but
two is enough) hunks for a binary patch.
The original "binary patch" output from git-diff is internally
parsed into an "is_binary" patch with one fragment. Upcoming
reversible binary patch output will have two fragments, the
first one being the forward patch and the second one the reverse
patch.
On Solaris and the BSDs the definition of "struct sockaddr_storage"
is not available from "netinet/in.h". On Solaris "sys/socket.h" is
enough, at least OpenBSD needs "sys/types.h", too.
Using "sys/types.h" and "sys/socket.h" seems to be a more portable
way.

gitweb: Change appereance of marker of refs pointing to given object
Change git_get_references to include type of ref in the %refs value, which
means putting everything after 'refs/' as a ref name, not only last
part of the name. Instead of separating refs pointing to the same
object by " / " separator, use anonymous array reference to store all
refs pointing to given object.
Use 'git-ls-remote .' if $projectroot/$project/info/refs does not
exist. (Perhaps it should be used always.)
Refs are now in separate span elements. Class is dependent on the ref
type: currently known classes are 'tag', 'head', 'remote', and 'ref'
(last one for HEAD and other refs in the main directory). There is
encompassing span element of class refs, just in case of unknown ref
type.
This might be considered cleaner separating of git_get_references into
filling %refs hash only, and not taking part in formatting ref marker.

Rename some of subroutines to better reflect what they do.
Some renames were not performed because subroutine name
reflects hash key.
Subroutines name guideline:
* git_ prefix for subroutines related to git commands,
git repository, or to gitweb actions
* git_get_ prefix for inner subroutines calling git command
or reading some file in the repository and returning some output
* parse_ prefix for subroutines parsing some text (or reading and
parsing some text) into hash or list
* format_ prefix for subroutines formatting, post-processing
or generating some HTML/text fragment
* _get_ infix for subroutines which return result
* _print_ infix for subroutines which print fragment of output
* _body suffix for subroutines which outputs main part (body)
of related action (usually table)
* _nav suffix for subroutines related to navigation bars
* _div suffix for subroutines returning or printing div element
* subroutine names should not be based on how the result is obtained,
as this might change easily
Add a newline before appending "Signed-off-by: " line
Whef the last line of the commit log message does not end with
"^[-A-Za-z]+: [^@]+@", append a newline after it to separate
the body of the commit log message from the run of sign-off and
ack lines. e.g. "Signed-off-by: A U Thor <au.thor@example.com>" or
"Acked-by: Me <myself@example.org>".
