Adhemerval Zanella 0e16969129 support: Add support_capture_subprogram
Its API is similar to support_capture_subprocess, but rather creates a
new process based on the input path and arguments.  Under the hoods it
uses posix_spawn to create the new process.

It also allows the use of other support_capture_* functions to check
for expected results and free the resources.

Checked on x86_64-linux-gnu.

	* support/Makefile (libsupport-routines): Add support_subprocess,
	xposix_spawn, xposix_spawn_file_actions_addclose, and
	xposix_spawn_file_actions_adddup2.
	(tst-support_capture_subprocess-ARGS): New rule.
	* support/capture_subprocess.h (support_capture_subprogram): New
	prototype.
	* support/support_capture_subprocess.c (support_capture_subprocess):
	Refactor to use support_subprocess and support_capture_poll.
	(support_capture_subprogram): New function.
	* support/tst-support_capture_subprocess.c (write_mode_to_str,
	str_to_write_mode, test_common, parse_int, handle_restart,
	do_subprocess, do_subprogram, do_multiple_tests): New functions.
	(do_test): Add support_capture_subprogram tests.
	* support/subprocess.h: New file.
	* support/support_subprocess.c: Likewise.
	* support/xposix_spawn.c: Likewise.
	* support/xposix_spawn_file_actions_addclose.c: Likewise.
	* support/xposix_spawn_file_actions_adddup2.c: Likewise.
	* support/xspawn.h: Likewise.

This subdirectory contains infrastructure which is not put into
installed libraries, but may be linked into programs (installed or
not) and tests.

# Error-checking wrappers

These wrappers test for error return codes an terminate the process on
error.  They are declared in these header files:

* support.h
* xsignal.h
* xthread.h

In general, new wrappers should be added to support.h if possible.
However, support.h must remain fully compatible with C90 and therefore
cannot include headers which use identifers not reserved in C90.  If
the wrappers need additional types, additional headers such as
signal.h need to be introduced.

# Test framework

The test framework provides a main program for tests, including a
timeout for hanging tests.  See README-testing.c for a minimal
example, and test-driver.c for details how to use it.  The following
header files provide related declarations:

* check.h
* temp_file.h
* test-driver.h
