This patch uses GDB self test in GDBserver. The self tests are run if
GDBserver is started with option --selftest.

The next patch moves selftest.c to common/selftest.c, so that GDBserver
can use it as well. However selftest.c uses something isn't "portable" on
GDB and GDBserver.
First, this patch removes QUIT. I don't expect that we type ctrl-c during
self/unit tests, and each test shouldn't take long time. Secondly, I
replace exception_fprintf and printf_filtered with debug_printf. Verified
that unit tests still catch fails.
gdb:
2017-08-18 Yao Qi <yao.qi@linaro.org>
* selftest.c (run_tests): Don't call QUIT. Call debug_printf
instead of exception_fprintf and printf_filtered.

GDB has some global variables, like sentinel_frame,
current_thread_arch, and etc, we need to reset them after each unit
tests.
gdb:
2017-05-24 Yao Qi <yao.qi@linaro.org>
* selftest-arch.c (tests_with_arch): Call registers_changed
and reinit_frame_cache.
* selftest.c (run_self_tests): Likewise.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.

This adds a unit test for the copy_bitwise function in dwarf2loc.c.
With the old (broken) version of copy_bitwise this test would generate
the following failure message:
(gdb) maintenance selftest
Self test failed: copy_bitwise 11000000 != 10000000 (7+2 -> 0)
gdb/ChangeLog:
2016-11-24 Andreas Arnez <arnez@linux.vnet.ibm.com>
Pedro Alves <palves@redhat.com>
* dwarf2loc.c (bits_to_str, check_copy_bitwise)
(copy_bitwise_tests): New functions.
(_initialize_dwarf2loc): Register the new function
copy_bitwise_tests as a unit test.
* selftest.c (run_self_tests): Improve the failure message's
wording and formatting.

This patch changes selftest.c to use std::vector rather than VEC.
I think this is a small net plus.
2016-10-12 Tom Tromey <tom@tromey.com>
* selftest.c: Include <vector>, not "vec.h".
(self_test_function_ptr): Remove.
(tests): Now a std::vector.
(register_self_test, run_self_tests): Update.

I wanted to unit test the Rust lexer, so I added a simple unit testing
command to gdb.
The intent is that self tests will only be compiled into gdb in
development mode. In release mode they simply won't exist. So, this
exposes $development to C code as GDB_SELF_TEST.
In development mode, test functions are registered with the self test
module. A test function is just a function that does some checks, and
throws an exception on failure.
Then this adds a new "maint selftest" command which invokes the test
functions, and a new dejagnu test case that invokes it.
