git clone <url> C:\cygwin\home\USER\repo' is working (again)
A regression for cygwin users was introduced with commit 05b458c,
"real_path: resolve symlinks by hand".
In the the commit message we read:
The current implementation of real_path uses chdir() in order to resolve
symlinks. Unfortunately this isn't thread-safe as chdir() affects a
process as a whole...
The old (and non-thread-save) OS calls chdir()/pwd() had been
replaced by a string operation.
The cygwin layer "knows" that "C:\cygwin" is an absolute path,
but the new string operation does not.
"git clone <url> C:\cygwin\home\USER\repo" fails like this:
fatal: Invalid path '/home/USER/repo/C:\cygwin\home\USER\repo'
The solution is to implement has_dos_drive_prefix(), skip_dos_drive_prefix()
is_dir_sep(), offset_1st_component() and convert_slashes() for cygwin
in the same way as it is done in 'Git for Windows' in compat/mingw.[ch]
Extract the needed code into compat/win32/path-utils.[ch] and use it
for cygwin as well.
