Original patch from Dmitry Goncharov <dgoncharov@users.sf.net>. When handling a fatal signal ensure the temporary files for stdin and the jobserver fifo (if in use) are deleted. * src/makeint.h (temp_stdin_unlink): Declare a new method. * src/main.c (temp_stdin_unlink): Delete the stdin temporary file if it exists. If the unlink fails and we're not handling a signal then show an error. (main): Call temp_stdin_unlink() instead of unlinking by hand. * src/commands.c (fatal_error_signal): Invoke cleanup methods if we're handling a fatal signal. * tests/scripts/features/output-sync: Test signal handling during output sync and jobserver with FIFO. * tests/scripts/features/temp_stdin: Test signal handling when makefiles are read from stdin.
