The code and tests assume that the system supplied iconv() would
always use BOM in its output when asked to encode to UTF-16 (or
UTF-32), but apparently some implementations output big-endian
without BOM. A compile-time knob has been added to help such
systems (e.g. NonStop) to add BOM to the output to increase
portability.

git-compat-util: work around fileno(fp) that is a macro
On various BSD's, fileno(fp) is implemented as a macro that directly
accesses the fields in the FILE * object, which breaks a function that
accepts a "void *fp" parameter and calls fileno(fp) and expect it to
work.
Work it around by adding a compile-time knob FILENO_IS_A_MACRO that
inserts a real helper function in the middle of the callchain.

utf8: handle systems that don't write BOM for UTF-16
When serializing UTF-16 (and UTF-32), there are three possible ways to
write the stream. One can write the data with a BOM in either big-endian
or little-endian format, or one can write the data without a BOM in
big-endian format.
Most systems' iconv implementations choose to write it with a BOM in
some endianness, since this is the most foolproof, and it is resistant
to misinterpretation on Windows, where UTF-16 and the little-endian
serialization are very common. For compatibility with Windows and to
avoid accidental misuse there, Git always wants to write UTF-16 with a
BOM, and will refuse to read UTF-16 without it.
However, musl's iconv implementation writes UTF-16 without a BOM,
relying on the user to interpret it as big-endian. This causes t0028 and
the related functionality to fail, since Git won't read the file without
a BOM.
Add a Makefile and #define knob, ICONV_OMITS_BOM, that can be set if the
iconv implementation has this behavior. When set, Git will write a BOM
manually for UTF-16 and UTF-32 and then force the data to be written in
UTF-16BE or UTF-32BE. We choose big-endian behavior here because the
tests use the raw "UTF-16" encoding, which will be big-endian when the
implementation requires this knob to be set.
Update the tests to detect this case and write test data with an added
BOM if necessary. Always write the BOM in the tests in big-endian
format, since all iconv implementations that omit a BOM must use
big-endian serialization according to the Unicode standard.
Preserve the existing behavior for systems which do not have this knob
enabled, since they may use optimized implementations, including
defaulting to the native endianness, which may improve performance.

The setup code uses octal values with printf to generate a BOM for
UTF-16/32 BE/LE. It specifically uses '\777' to emit a 0xff byte. This
relies on the fact that most shells truncate the value above 0o377.
Ash however interprets '\777' as '\77' + a literal '7', resulting in an
invalid BOM.
Fix this by using the proper value of 0xff: '\377'.

The reason for killing gpg-agent is given in 29ff1f8f74 ("t: lib-gpg:

When running gpg-relevant tests, a gpg-daemon is spawned for each
GNUPGHOME used. This daemon may stay running after the test and cache
file descriptors for the trash directories, even after the trash
directory is removed. This leads to ENOENT errors when attempting to
create files if tests are run multiple times.
Add a cleanup script to force flushing the gpg-agent for that GNUPGHOME
(if any) before setting up the GPG relevant-environment.
Killing gpg-agent once per test is sufficient.

Commit 2c8921db2b (travis-ci: build with the right compiler,

2019-01-27) started to use MAKEFLAGS as well. Unfortunately, there is
a semantic conflict between these two commits: both of them set
MAKEFLAGS, and since the line adding CC from 2c8921db2b comes later in
'ci/lib.sh', it overwrites the number of parallel jobs added in eaa62291ff.
Consequently, since both commits have been merged all our CI jobs have
been building Git, building its documentation, and applying semantic
patches sequentially, making all build jobs a bit slower. Running
the test suite is unaffected, because the number of test jobs comes
from GIT_PROVE_OPTS.

the number of parallel jobs to use is preserved.

Commit 9e5da3d055 (add: use separate ADD_CACHE_RENORMALIZE flag,
2019-01-17) switched out using HASH_RENORMALIZE in our flags field for a
new ADD_CACHE_RENORMALIZE flag. However, it forgot to convert one of the
checks for HASH_RENORMALIZE into the new flag, which totally broke "git
add --renormalize".
To make matters even more confusing, the resulting code would racily
pass the tests! The forgotten check was responsible for defeating the
up-to-date check of the index entry. That meant that "git add
--renormalize" would refuse to renormalize things that appeared
stat-clean. But most of the time the test commands run fast enough that
the file mtime is the same as the index mtime. And thus we err on the
conservative side and re-hash the file, which is what "--renormalize"
would have wanted.
But if you're unlucky and cross that one-second boundary between writing
the file and writing the index (which is more likely to happen on a slow
or heavily-loaded system), then the file appears stat-clean. And
"--renormalize" would effectively do nothing.
The fix is straightforward: convert this check to use the right flag.

remote-curl: tighten "version 2" check for smart-http
In a v2 smart-http conversation, the server should reply to our initial

starts_with(), but really that should be the only thing in that packet.
A response of "version 20" should not match.

After making initial contact with an http server, we have to decide if
the server supports smart-http, and if so, which version. Our rules are
a bit inconsistent:
1. For v0, we require that the content-type indicates a smart-http
response. We also require the response to look vaguely like a
pkt-line starting with "#". If one of those does not match, we fall
back to dumb-http.
But according to our http protocol spec[1]:
Dumb servers MUST NOT return a return type starting with
`application/x-git-`.
If we see the expected content-type, we should consider it
smart-http. At that point we can parse the pkt-line for real, and
complain if it is not syntactically valid.
2. For v2, we do not actually check the content-type. Our v2 protocol
spec says[2]:
When using the http:// or https:// transport a client makes a
"smart" info/refs request as described in `http-protocol.txt`[...]
and the http spec is clear that for a smart-http response[3]:
The Content-Type MUST be `application/x-$servicename-advertisement`.
So it is required according to the spec.
These inconsistencies were easy to miss because of the way the original
code was written as an inline conditional. Let's pull it out into its
own function for readability, and improve a few things:
- we now predicate the smart/dumb decision entirely on the presence of
the correct content-type
- we do a real pkt-line parse before deciding how to proceed (and die
if it isn't valid)
- use skip_prefix() for comparing service strings, instead of
constructing expected output in a strbuf; this avoids dealing with
memory cleanup
Note that this _is_ tightening what the client will allow. It's all
according to the spec, but it's possible that other implementations
might violate these. However, violating these particular rules seems
like an odd choice for a server to make.

Revert "rebase: introduce a shortcut for --reschedule-failed-exec"
This patch was contributed only as a tentative "we could introduce a

to show a warning in the near future, and flip the default
