Add new files.

2000-10-09  Havoc Pennington  <hp@redhat.com>

        * Makefile.am, tests/Makefile.am: Add new files.

	* tests/spawn-test.c, tests/shell-test.c: new tests for
	the shell/spawn stuff

	* gutils.c (g_find_program_in_path): convert a relative
	program name into an absolute pathname to an existing
	executable

	* gspawn.h, gspawn.c: New fork/exec API

	* gshell.h, gshell.c: Shell-related utilities, at the moment
	simply routines to parse argv and quote/unquote strings

	* guniprop.c (g_unichar_isspace): Return TRUE for the
	ASCII space characters isspace() returns TRUE for.

	* gfileutils.c (g_file_get_contents): Convenience function
	to slurp entire file into a string and return it. Partially
	written by Joel Becker.
	(g_file_test): file test function
