- Make sure that "X:" paths are not handled as absolute DOS paths in
fstatat and other ...at calls. "X:/" still is handled as absolute
path.

Cygwin: dllfixdbg: create .gnu_debuglink section in the right spot A recent change in binutils marks the .gnu_debuglink_overlay section as debug section. When dllfixdbg calls objcopy -g, the section is removed and the --add-gnu-debuglink option on the same command line appends the section consequentially at the end of the sections. This in turn breaks Windows Version info and, potentially, raising the cygheap size at runtime. Fix this by adding an explicit --keep-section=.gnu_debuglink_overlay to the objcopy command line.

Cygwin: console: Handle Unicode surrogate pairs. When running Cygwin's Bash in the Windows Terminal (see https://docs.microsoft.com/en-us/windows/terminal/ for details), Cygwin is receiving keyboard input in the form of UTF-16 characters. UTF-16 has that awkward challenge that it cannot map the full Unicode range, and to make up for it, there are the ranges U+D800-U+DBFF and U+DC00-U+DFFF which are illegal except when they come in a pair encoding for Unicode characters beyond U+FFFF. Cygwin does not handle such surrogate pairs correctly at the moment, as can be seen e.g. when running Cygwin's Bash in the Windows Terminal and then inserting an emoji (e.g. via Windows + <dot>, which opens an emoji picker on recent Windows versions): Instead of showing an emoji, this shows the infamous question mark in a black triangle, i.e. the invalid Unicode character. Let's special-case surrogate pairs in this scenario. This fixes https://github.com/git-for-windows/git/issues/3281 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

- Handle Unicode surrogate pairs in console. Cygwin console does not
handle surrogate pairs correctly at the moment. Fix issue that
running bash in Windows Terminal and inserting an emoji does not
work as expected.

Cygwin: fix up cached DOS file attributes after file creation The file attributes after creating a file are not necessarily identical to the attributes we passed as argument to NtCreateFile. This results in subsequent operations like fchmod or facl to set the DOS file attributes to unexpected values. The fix is to request file attributes from the OS after file creation and cache those.

- Fix long-standing problem that fchmod or facl on newly created files
screw up the DOS file attributes.

Cygwin: pipe: Handle STATUS_PENDING even for nonblocking mode. - NtReadFile() and NtWriteFile() seems to return STATUS_PENDING occasionally even in nonblocking mode. This patch adds handling for STATUS_PENDING in nonblocking mode. Addresses: https://cygwin.com/pipermail/cygwin/2021-November/249910.html

- Fix issue that pipe read()/write() occasionally returns a garbage
length when NtReadFile/NtWriteFile returns STATUS_PENDING in non-
blocking mode.
