The setjmp() function doesn't specify whether signal masks are saved and
restored; on Linux they are not, but on BSD (including MacOSX) they are.
We want to have consistent behaviour across platforms, so we should
always use "don't save/restore signal mask" (this is also generally
going to be faster). This also works around a bug in MacOSX where the
signal-restoration on longjmp() affects the signal mask for a completely
different thread, not just the mask for the thread which did the longjmp.
The most visible effect of this was that ctrl-C was ignored on MacOSX
because the CPU thread did a longjmp which resulted in its signal mask
being applied to every thread, so that all threads had SIGINT and SIGTERM
blocked.

The POSIX-sanctioned portable way to do a jump without affecting signal
masks is to siglongjmp() to a sigjmp_buf which was created by calling
sigsetjmp() with a zero savemask parameter, so change all uses of
setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0)
to save the signal mask; however the following siglongjmp() must not
restore the signal mask, so the pair can be effectively considered as
"sigjmp/longjmp which don't touch the mask".]

For Windows we provide a trivial sigsetjmp/siglongjmp in terms of
setjmp/longjmp -- this is OK because no user will ever pass a non-zero
savemask.

The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c
are left untouched because these are self-contained singlethreaded
test programs intended to be run under QEMU's Linux emulation, so they
have neither the portability nor the multithreading issues to deal with.

Add explicit braces round an empty for-loop body; this fits
QEMU style and is easier to read than an inconspicuous semicolon
at the end of the line. It also silences a clang warning:

          for (i = 0; tmp[i] == '0' && tmp[i + 1]; i++);

Remove the function qemu_log_try_set_file() and its users (which
are all in TCG code generation functions for various targets).
This function was added to abstract out code which was originally
written as "if (!logfile) logfile = stderr;" in order that BUG:
case code which did an unguarded "fprintf(logfile, ...)" would
not crash if debug logging was not enabled. Since those direct
uses of logfile have also been abstracted away into qemu_log()
calls which check for a NULL logfile, there is no need for the
target-* files to mess with the user's chosen logging settings.
