These fixes were necessary for Sverre Rabbelier's remote-hg to work,
but for some magic reason they are not necessary for the current
remote-hg. Makes you wonder how that one gets away with it.

Our current version of bash 3.1.17(5) can not parse the following snippet
correctly
p=abcd
abspath=/$p
subdir="x$(echo "$p" | tail -c $((253 - ${#abspath})))"
as it returns
tail: cannot open `253' for reading: No such file or directory
This is fixed in bash 3.1.20(4), I did not check earlier versions.

Windows paths are typically limited to MAX_PATH = 260 characters, even
though the underlying NTFS file system supports paths up to 32,767 chars.
This limitation is also evident in Windows Explorer, cmd.exe and many
other applications (including IDEs).
Particularly annoying is that most Windows APIs return bogus error codes
if a relative path only barely exceeds MAX_PATH in conjunction with the
current directory, e.g. ERROR_PATH_NOT_FOUND / ENOENT instead of the
infinitely more helpful ERROR_FILENAME_EXCED_RANGE / ENAMETOOLONG.
Many Windows wide char APIs support longer than MAX_PATH paths through the
file namespace prefix ('\\?\' or '\\?\UNC\') followed by an absolute path.
Notable exceptions include functions dealing with executables and the
current directory (CreateProcess, LoadLibrary, Get/SetCurrentDirectory) as
well as the entire shell API (ShellExecute, SHGetSpecialFolderPath...).
Introduce a handle_long_path function to check the length of a specified
path properly (and fail with ENAMETOOLONG), and to optionally expand long
paths using the '\\?\' file namespace prefix. Short paths will not be
modified, so we don't need to worry about device names (NUL, CON, AUX).
Contrary to MSDN docs, the GetFullPathNameW function doesn't seem to be
limited to MAX_PATH (at least not on Win7), so we can use it to do the
heavy lifting of the conversion (translate '/' to '\', eliminate '.' and
'..', and make an absolute path).
Add long path error checking to xutftowcs_path for APIs with hard MAX_PATH
limit.
Add a new MAX_LONG_PATH constant and xutftowcs_long_path function for APIs
that support long paths.
While improved error checking is always active, long paths support must be
explicitly enabled via 'core.longpaths' option. This is to prevent end
users to shoot themselves in the foot by checking out files that Windows
Explorer, cmd/bash or their favorite IDE cannot handle.
Test suite:
Test the case is when the full pathname length of a dir is close
to 260 (MAX_PATH).

There are some issues with the git-svn test cases when they are
being run on windows under a MINGW build. Some things are not
available like the changing of the execute flag of shell scripts
via the chmod command. Also there were problems with folder names
that end with a dot on windows.

As per https://msdn.microsoft.com/en-us/library/x99tb11d.aspx:
The set of available locale names, languages, country/region
codes, and code pages includes all those supported by the Windows
NLS API except code pages that require more than two bytes per
character, such as UTF-7 and UTF-8.
Therefore, MinGW gettext cannot cope with UTF-8 at all, because it uses
the Win32 API internally.
However, when the test asks `locale -a` it reports that is_US.utf8 is
available, because that `locale` is actually an *MSys2* program (and MSys2
can cope with UTF-8 alright).
Let's just skip this test for MinGW Git altogether.

There is a MinGW gettext.exe, but still no MinGW locale.exe. Instead the
MSys2 locale.exe kicks in, which corresponds to the MSys2 gettext.exe,
however. Therefore some assumptions of t0200 cannot be fulfilled when
running inside MSys2.

Without this patch, t0027 expects the native end-of-lines to be a single
line feed character. On Windows, however, we set it to a carriage return
character followed by a line feed character. Thus, we have to modify
t0027 to expect different warnings depending on the end-of-line markers.

A string of the form "@/abcd" is considered a file path
by the msys layer and therefore translated to a windows path.
Here the trick is to double the slashes.
The msys patch translation can be studied with the following
test program:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
unsigned int i;
for(i=1; i < argc; i++)
printf("argv[%d]=%s\n",i, argv[i]);
exit(0);
}

MSys works very hard to convert Unix-style paths into DOS-style ones.
*Very* hard.
So hard, indeed, that
git blame -L/hello/,/green/
is translated into something like
git blame -LC:/msysgit/hello/,C:/msysgit/green/
As seen in msys_p2w in src\msys\msys\rt\src\winsup\cygwin\path.cc, line
3204ff:
case '-':
//
// here we check for POSIX paths as attributes to a POSIX switch.
//
...
seemingly absolute POSIX paths in single-letter options get expanded by
msys.dll unless they contain '=' or ';'.
So a quick and very dirty fix is to use '-L/;*evil/'. (Using an equal sign
works only when it is before a comma, so in the above example, /=*green/
would still be converted to a DOS-style path.)

Apparently the signal handling is not quite correct in the fsckobject
handling (most likely we rely on a side effect that lets us still output
some message after receiving a signal 13 but in the BuildHive setup this
fails intermittently).
As a consequence, the push in t5504 does fail as expected, but fails to
output anything (unexpected). Since this is good enough for now, let's
handle an empty output as success, too.

This happens only when the corresponding commits are not exported in
the current fast-export run. This can happen either when the relevant
commit is already marked, or when the commit is explicitly marked
as UNINTERESTING with a negative ref by another argument.
This breaks fast-export basec remote helpers.

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.

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.

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.
