support: Introduce new subdirectory for test infrastructure The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected.

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
support: Add xclock_gettime * support/xclock_gettime.c (xclock_gettime): New file. Provide clock_gettime wrapper for use in tests that fails the test rather than returning failure. * support/xtime.h: New file to declare xclock_gettime. * support/Makefile: Add xclock_gettime.c. * support/README: Mention xtime.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
support: Add timespec.h It adds useful functions for tests that use struct timespec. Checked on x86_64-linux-gnu and i686-linux-gnu. * support/timespec.h: New file. Provide timespec helper functions along with macros in the style of those in check.h. * support/timespec.c: New file. Implement check functions declared in support/timespec.h. * support/timespec-add.c: New file from gnulib containing timespec_add implementation that handles overflow. * support/timespec-sub.c: New file from gnulib containing timespec_sub implementation that handles overflow. * support/README: Mention timespec.h.

For tests that make use of struct timespec, the following header files
contain additional macros and helper functions:
* timespec.h
