Cygwin: path_conv: make sure sym.path_flags is always initialized Commit c1023ee353705 introduced a split between mount flags and path flags. It didn't initialize symlink_info::path_flags in path_conv::check, because that's done in symlink_info::check. However, there are two code paths expecting symlink_info::path_flags being already initialized and both skip symlink_info::check. Make sure symlink_info::path_flags is initalized to 0 early in path_conv::check.

Bug Fixes
---------
- Fix an uninitialized variable having weird side-effects in path handling.

Cygwin: console: Fix hangup of less on quit after the window is resized. https://cygwin.com/pipermail/cygwin/2022-December/252737.html If the less is started from non-cygwin shell and window size is changed, it will hang-up when quitting. The cause of the proglem is that less uses longjump() in signal handler. If the signal handler is called while cygwin is acquiring the mutex, cygwin loses the chance to release mutex. With this patch, the mutex is released just before calling kill_pgrp() and re-acquired when kill_pgrp() returns.

Cygwin: reinstantiate exporting _alloca This basically reverts commit 1556b96b1b3b03112f271dfe30e043ed538354fd. Turns out that _alloca is actually used, for instance, by clang.

Cygwin: /proc/<PID>/status: avoid crash computing signal info The code computing the mask of pending signals used the per-queued signal TLS pointer without checking it for NULL. Fix this by using the process-wide signal mask in that case.
