【背景】
sigaction参数sa_mask的设置方法不符合设置本意，某种情况下会导致进程屏蔽字被覆盖
【修改方案】
修改设置方法，在handle处理前设置屏蔽字，处理后恢复屏蔽字

【影响】
如果用户在handle中设置了屏蔽字，该屏蔽字会在handle结束时会被覆盖掉。已测试了所有
相关用例，均可通过。待在linux验证确认是问题后修复。

because struct stat is no longer assumed to correspond to the
structure used by the stat-family syscalls, it's not valid to make any
of these syscalls directly using a buffer of type struct stat.

commit 94938920 moved all logic around
this change for stat-family functions into fstatat.c, making the
others wrappers for it. but a few other direct uses of the syscall
were overlooked. the ones in tmpnam/tempnam are harmless since the
syscalls are just used to test for file existence. however, the uses
in fchmodat and __map_file depend on getting accurate file properties,
and these functions may actually have been broken one or more mips
variants due to removal of conversion hacks from syscall_arch.h.

as a low-risk fix, simply use struct kstat in place of struct stat in
the affected places.

these did not truncate excess precision in the return value. fixing
them looks like considerable work, and the current C code seems to
outperform them significantly anyway.

long double functions are left in place because they are not subject
to excess precision issues and probably better than the C code.

this commit is for the sake of reviewable history.

analogous to commit 1c9afd69 for
atan[2][f].

for functions implemented in C, this is a requirement of C11 (F.6);
strictly speaking that text does not apply to standard library
functions, but it seems to be intended to apply to them, and C2x is
expected to make it a requirement.

failure to drop excess precision is particularly bad for inverse trig
functions, where a value with excess precision can be outside the
range of the function (entire range, or range for a particular
subdomain), breaking reasonable invariants a caller may expect.

this extends commit 5a105f19, removing
timer[fd]_settime and timer[fd]_gettime. the timerfd ones are likely
to have been used in software that started using them before it could
rely on libc exposing functions.
