Minor updates to profiler and gmondump, which share some code:
- fix operation of error() so it actually works as intended
- resize 4K-size auto buffer reservations to BUFSIZ (==1K)
- remove trailing '\n' from 2nd arg on error() calls everywhere
- provide consistent annotation of Windows error number displays

Takashi Yano 3d94e07c49 newlib: libc: Fix crash on fprintf to a wide-oriented stream.
Previously, fprintf() on a wide-oriented stream crashes or outputs
garbage. This is because a narrow char string which can be odd bytes
in length is cast into a wide char string which should be even
bytes in length in __sprint_r/__sfputs_r based on the __SWID flag.
As a result, if the length is odd bytes, the reading buffer runs over
the buffer length, which causes a crash. If the length is even bytes,
garbage is printed.

With this patch, any output to the stream which is set to different
orientation fails with error just like glibc. Note that it behaves
differently from other libc implementations such as BSD, musl and
Solaris.

Corinna Vinschen 2ef627c46e Cygwin: let feraiseexcept actually raise an exception
The exception handling inside of Cygwin functions marked as SIGFE
covers exceptions and lets the library code handle them gracefully.
If these functions want to raise an exception, they have to send a
signal explicitely via raise(3).

That's not what we want in feraiseexcept(). It triggers a floating
point exception explicitely by calling the i387 op "fwait".  Being
marked as SIGFE, this exception will be suppressed and the normal
exception handling won't kick in.

Fix this by moving feraiseexcept into the NOSIGFE realm.

Corinna Vinschen 60d1eeac6c Cygwin: cwd: avoid releasing the cwdstuff SRW Lock twice
cwdstuff::set has a code snippet handling the case where a process
can't create a handle to a directory, e. g., due to permissions.

Commit 88443b0a22 ("cwdstuff: Don't leave from setting the CWD
prematurely on init") introduced a special case to handle this
situation at process initialization. It also introduces an early
mutex release, which is not required, but ok, because we're in the
init phase. Releasing the mutex twice is no problem since the mutexes
are recursive.

Fast forward to commit 0819679a7a ("Cygwin: cwd: use SRWLOCK
instead of muto"). The mechanical change from a recursive mutex
to a non-recursive SRWLOCK failed to notice that this very specific
situation will release the SRWLOCK twice.

Remove the superfluous release action. While at it, don't set dir to
NULL, but h, since dir will get the value of h anyway later on.
Setting h to NULL may not be necessary, but better safe than sorry.

Takashi Yano d56d58ace2 Cygwin: dsp: Improve minimum buffser size estimation.
The commit 322c7150b2 restricts buffer size with a fixed length,
however, the minimum buffer size should be varied by the sample rate.
With this patch, it is estimated using sample rate, sample width
and number of channels so that the buffer length is not less than
80 msec which is almost the minimum value of Win MME to work.

Corinna Vinschen c0aa6ac30e Cygwin: NFS: create devices (especially FIFOs) as shortcut files
Creating real NFS symlinks for device files has a  major downside:
The way we store device info requires to change the symlink target
in case of calling chmod(2). This falls flat in two ways:

- It requires to remove and recreate the symlink, so it doesn't
  exist for a short period of time, and
- removing fails badly if there's another open handle to the symlink.

Therefore, change this to create FIFOs as shortcut files, just as on
most other filesystems.  Make sure to recognize these new shortcuts
on NFS (for devices only) in path handling and readdir.

FIFOs on NFS were never recogized as such in path handling.

stat(2) indicated native FIFOs as FIFOs but the path handling
code didn't set the matching values in the inner symlink checking
code, so the followup behaviour was wrong.

Basically for the same reason, Cygwin-created FIFOs were just treated
as symlinks with weird content by stat(2) as well as path handling.
