submodules: add the lib-submodule-update.sh test library
Add this test library to simplify covering all combinations of submodule
update scenarios without having to add those to a test of each work tree
manipulating command over and over again.
The functions test_submodule_switch() and test_submodule_forced_switch()
are intended to be called from a test script with a single argument. This
argument is either a work tree manipulating command (including any command
line options) or a function (when more than a single git command is needed
to switch work trees from the current HEAD to another commit). This
command (or function) is passed a target branch as argument. The two new
functions check that each submodule transition is handled as expected,
which currently means that submodule work trees are not affected until
"git submodule update" is called. The "forced" variant is for commands
using their '-f' or '--hard' option and expects them to overwrite local
modifications as a result. Each of these two functions contains 14
tests_expect_* calls.
Calling one of these test functions the first time creates a repository
named "submodule_update_repo". At first it contains two files, then a
single submodule is added in another commit followed by commits covering
all relevant submodule modifications. This repository is newly cloned into
the "submodule_update" for each test_expect_* to avoid interference
between different parts of the test functions (some to-be-tested commands
also manipulate refs along with the work tree, e.g. "git reset").
Follow-up commits will then call these two test functions for all work
tree manipulating commands (with a combination of all their options
relevant to what they do with the work tree) making sure they work as
expected. Later this test library will be extended to cover merges
resulting in conflicts too. Also it is intended to be easily extendable
for the recursive update functionality, where even more combinations of
submodule modifications have to be tested for.
This version documents two bugs in current Git with expected failures:
*) When a submodule is replaced with a tracked file of the same name the
submodule work tree including any local modifications (and even the
whole history if it uses a .git directory instead of a gitfile!) is
silently removed.
*) Forced work tree updates happily manipulate files in the directory of a
submodule that has just been removed in the superproject (but is of
course still present in the work tree due to the way submodules are
currently handled). This becomes dangerous when files in the submodule
directory are overwritten by files from the new superproject commit, as
any modifications to the submodule files will be lost) and is expected
to also destroy history in the - admittedly unlikely case - the new
commit adds a file named ".git" to the submodule directory.

refs.c: change ref_transaction_update() to do error checking and return status

error. There are currently no conditions in _update that will return error but
there will be in the future. Add an err argument that will be updated on
failure. In future patches we will start doing both locking and checking
for name conflicts in _update instead of _commit at which time this function
will start returning errors for these conditions.
Also check for BUGs during update and die(BUG:...) if we are calling
_update with have_old but the old_sha1 pointer is NULL.

t/Makefile: always test all lint targets when running tests
Only the two targets "test-lint-duplicates" and "test-lint-executable" are
currently executed when running the test target. This was done on purpose
when the TEST_LINT variable was added in 81127d74 to avoid twisted shell
scripting by developers only to avoid false positives that might result
from the rather simple minded tests, e.g. test-lint-shell-syntax. But it
looks like it might be better to include all lint tests to help developers
to detect non portable shell constructs before the patch is sent to the
list and reviewed there.
Change the TEST_LINT variable to run all lint test unless the TEST_LINT
variable is overridden. If we hit false positives more often than helping
developers to avoid non-portable code (or add less accurate or slow tests
later) we could still fall back to exclude them like 81127d74 proposed.

remote-curl: mark helper-protocol errors more clearly
When we encounter an error in remote-curl, we generally just
report it to stderr. There is no need for the user to care
that the "could not connect to server" error was generated
by git-remote-https rather than a function in the parent
git-fetch process.
However, when the error is in the protocol between git and
the helper, it makes sense to clearly identify which side is
complaining. These cases shouldn't ever happen, but when
they do, we can make them less confusing by being more
verbose.

We usually prefix our error messages with "error: ", but
many error messages from remote-curl are simply printed with
fprintf. This can make the output a little harder to read
(especially because such message may be intermingled with
errors from the parent git process).
There is no reason to avoid error(), as we are already
calling it many places (in addition to libgit.a functions
which use it).
While we're adjusting the messages, we can also drop the
capitalization which makes them unlike other git error
messages.

remote-curl: do not complain on EOF from parent git
The parent git process is supposed to send us an empty line
to indicate that the conversation is over. However, the
parent process may die() if there is a problem with the
operation (e.g., we try to fetch a ref that does not exist).
In this case, it produces a useful message, but then
remote-curl _also_ produces an unhelpful message:
$ git pull origin matser
fatal: couldn't find remote ref matser
Unexpected end of command stream
The "right" way to fix this is to teach the parent git to
always cleanly close the connection to the helper, letting
it know that we are done. Implementing that is rather
clunky, though, as it would involve either replacing die()
operations with returning errors up the stack (until we
disconnect the transport), or adding an atexit handler to
clean up any transport helpers left open.
It's much simpler to just suppress the EOF message in
remote-curl. It was not added to address any real-world
situation in the first place, but rather a "we should
probably report unexpected things" suggestion[1].
It is the parent git which drives the operation, and whose
exit value actually matters. If the parent dies, then the
helper has no need to complain (except as a debugging aid).
In the off chance that the pipe is closed without the parent
dying, it can still notice the non-zero exit code.
