signalblocking: simplify and remove gl_SILENT
gl_SILENT was problematic because if a trap was sprung, stderr
generated during the trap was lost. Avoid the problem by
removing the need for gl_SILENT.
* m4/gnulib-common.m4 (GL_TMP_FD, gl_SILENT): Remove.
* m4/signalblocking.m4 (gl_SIGNALBLOCKING):
Simplify, avoiding the need for gl_SILENT while preserving the
ability of the user to override the value of the cache variable,
now ac_cv_func_sigprocmask.
