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.
