Subject: [PATCH] GDB testsuite: More fixes for warnings with -std=gnu11

Fix some more C compiler warnings for missing function return types
and implicit function declarations in the GDB testsuite.

gdb/testsuite/ChangeLog:

	* gdb.base/bp-permanent.c: Include unistd.h.
	* gdb.python/py-framefilter-mi.c (main): Add return type.
	* gdb.python/py-framefilter.c (main): Likewise.
	* gdb.trace/actions-changed.c (main): Likewise.
