There are platforms (e.g. NonStop) that lack /dev/zero; use the
generate_zero_bytes helper we just introduced to append stream
of NULs at the end of the file.
The original, even though it uses "dd seek=... count=..." to make it
look like it is overwriting the middle part of an existing file, has
truncated the file before this step with another use of "dd", which
may make it tricky to see why this rewrite is a correct one.

The get_oid_with_context() function is declared to return an enum in
cache.h, but defined to return an int in sha1-name.c. The compiler
notices this on AIX and rejects the build, since d1dd94b308 (Do not
print 'dangling' for cat-file in case of ambiguity - 2019-01-17) was
merged.

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.

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'.

Use a '!' character to start a non-matching pattern bracket
expression, as specified by POSIX in Shell Command Language section
2.13.1 Patterns Matching a Single Character [1].
I used '^' instead in three places in the previous three commits, to
verify that the arguments of the '--stress=' and '--stress-limit='
options and the values of various '*_PORT' environment variables are
valid numbers. With certain shells, at least with dash (upstream and
in Ubuntu 14.04) and mksh, this led to various undesired behaviors:
# error message in case of a valid number
$ ~/src/dash/src/dash ./t3903-stash.sh --stress=8
error: --stress=<N> requires the number of jobs to run
# not the expected error message
$ ~/src/dash/src/dash ./t3903-stash.sh --stress=foo
./t3903-stash.sh: 238: test: Illegal number: foo
# no error message at all?!
$ mksh ./t3903-stash.sh --stress=foo
$ echo $?
0
Some other shells, e.g. Bash (even in posix mode), ksh, dash in Ubuntu
16.04 or later, are apparently happy to accept '^' just as well.

Let's suppose that a test somehow becomes flaky between 'master' and
'pu', and tends to fail within the first 50 repetitions when run with
'--stress'. In such a case we could use 'git bisect' to find the
culprit: if the test script fails with '--stress', then the commit is
definitely bad, but if it survives, say, 300 repetitions, then we could
consider it good with reasonable confidence.
Unfortunately, all this could only be done manually, because
'--stress' would run the test script repeatedly for all eternity on a
good commit, and it would exit with success even when it found a
failure on a bad commit.
So let's make '--stress' usable with 'git bisect run':
- Make it exit with failure if a failure is found.
- Add the '--stress-limit=<N>' option to repeat the test script
at most N times in each of the parallel jobs, and exit with
success when the limit is reached.
And then we could simply run something like:
$ git bisect start origin/pu master
$ git bisect run sh -c 'make && cd t &&
./t1234-foo.sh --stress --stress-limit=300'
Sure, as a brand new feature it won't be any useful right now, but in
a release or three most cooking topics will already contain this, so
we could automatically bisect at least newly introduced flakiness.

In 53fc999306 ("gpg-interface t: extend the existing GPG tests with
GPGSM", 2018-07-20), the gpgconf call which kills gpg-agent was copied
from the existing gpg setup code.
The reason for killing gpg-agent is given in 29ff1f8f74 ("t: lib-gpg:
flush gpg agent on startup", 2017-07-20):
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.

When gpgsm is installed, lib-gpg.sh attempts to update trustlist.txt to
relax the checking of some root certificate requirements. The path to
"${GNUPGHOME}" contains spaces which cause an "ambiguous redirect"
warning when bash is used to run the tests:
$ bash t7030-verify-tag.sh
/git/t/lib-gpg.sh: line 66: ${GNUPGHOME}/trustlist.txt: ambiguous redirect
ok 1 - create signed tags
ok 2 # skip create signed tags x509 (missing GPGSM)
...
No warning is issued when using bash called as /bin/sh, dash, or mksh.
Quote the path to ensure the redirect works as intended and sets the
GPGSM prereq. While we're here, drop the space after ">>".

Commit 2c8921db2b (travis-ci: build with the right compiler,
2019-01-17) started to use MAKEFLAGS to specify which compiler to use
to build Git. A bit later, and in a different topic branch commit
eaa62291ff (ci: inherit --jobs via MAKEFLAGS in run-build-and-tests,
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.
Append to MAKEFLAGS when setting the compiler to use, to ensure that
the number of parallel jobs to use is preserved.
