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.

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.

Commit c1023ee353 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.
