The previous implementation said that the filesystem information on
Windows is not reliable to determine whether a file is executable.
To find gather this information it was peeking into the first two bytes
of a file to see whether it looks executable.
Apart from the fact that on Windows executables are usually defined as
such by their extension it lead to slow opening of help file in some
situations.
When you have virus scanner running calling open on an executable file
is a potentially expensive operation. See the following measurements (in
seconds) for example.
With virus scanner running (coldcache):
$ ./a.exe /libexec/git-core/
before open (git-add.exe): 0.000000
after open (git-add.exe): 0.412873
before open (git-annotate.exe): 0.000175
after open (git-annotate.exe): 0.397925
before open (git-apply.exe): 0.000243
after open (git-apply.exe): 0.399996

before open (git-blame.exe): 0.000160
after open (git-blame.exe): 0.399136
...
With virus scanner running (hotcache):
$ ./a.exe /libexec/git-core/
before open (git-add.exe): 0.000000
after open (git-add.exe): 0.000325

This test did just list the given directory and open() each file in it.
With this patch I get:
$ time git help git
Launching default browser to display HTML ...
real 0m8.723s
user 0m0.000s
sys 0m0.000s
and without
$ time git help git

real 1m37.734s
user 0m0.000s

both tests with cold cache and giving the machine some time to settle
down after restart.

This test assumed that there are no two equivalent directory separators.
However, on Windows, the back slash and the forward slash *are*
equivalent. Let's paper over this issue by converting the backward
slashes to forward ones in the test that fails with MSys2 otherwise.

When shell scripts access a $TMP variable containing backslashes, they
will be mistaken for escape characters. Let's not let that happen by
converting them to forward slashes.
This fixes t7800 with MSys2.

There is a really useful debugging technique developed by Sverre
Rabbelier that inserts "bash &&" somewhere in the test scripts, letting
the developer interact at given points with the current state.
Another debugging technique, used a lot by this here coder, is to run
certain executables via gdb by guarding a "gdb -args" call in
bin-wrappers/git.
Both techniques were disabled by 781f76b1(test-lib: redirect stdin of
tests).
Let's reinstate the ability to run an interactive shell by making the
redirection optional: setting the TEST_NO_REDIRECT environment variable
will skip the redirection.

This test is susceptible to MSys2's posix-to-windows path mangling; Let's

With MSys2, there is actually an implementation of mkfifo available. The
only problem is that it is only emulating named pipes through the MSys2
runtime; The Win32 API has no idea about named pipes, hence the Git
executable cannot access those pipes either.
The symptom is that Git fails with a '<name>: No such file or directory'
because MSys2 emulates named pipes through special-crafted '.lnk' files.
The solution is to tell the test suite explicitly that we cannot use
named pipes when we want to test a MinGW Git.

MSys2 actually allows to create files or directories whose names contain
tabs, newlines or colors, even if plain Win32 API cannot access them.
As we are using an MSys2 bash to run the tests, such files or
directories are created successfully, but Git has no chance to work with
them because it is a regular Windows program, hence limited by the Win32
API.

With MSys2, the "TZ" environment variable gets filtered out when calling
non-MSys2 executables. The reason is that Windows' time zone handling is
substantially different from the POSIX one.
However, we just taught Git for Windows' fork of the MSys2 runtime to
pass on the timezone in a different environment variable, MSYS2_TZ for
the sole purpose of Git being able to reinterpret it correctly.

The unsetenv code has no idea to update our environ_size, therefore
causing segmentation faults when environment variables are removed
without compat/mingw.c's knowing (MinGW's optimized lookup would try
to strcmp() against NULL in such a case).

MSys2's strace facility is very useful for debugging... With this patch,
the bash will be executed through strace if the environment variable
GIT_STRACE_COMMANDS is set, which comes in real handy when investigating
issues in the test suite.
