Fix memory leaks in "test-tool regex" which have been there since
c91841594c (test-regex: Add a test to check for a bug in the regex
routines, 2012-09-01), as a result we can mark a test as passing with
SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true".
We could regfree() on the die() paths here, which would make some
invocations of valgrind(1) happy, but let's just target SANITIZE=leak
for now. Variables that are still reachable when we die() are not
reported as leaks.

7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27)
adds a REG_ILLSEQ prerequisite to avoid failures from the tests added in
4e2443b181 (log tests: test regex backends in "--encode=<enc>" tests,
2019-06-28), but hardcodes it to be only enabled in FreeBSD.
Instead of hardcoding the affected platform, teach the test-regex helper,
how to validate a pattern and report back, so it can be used to detect the
same issue in other affected systems (like DragonFlyBSD or macOS).
While at it, refactor the tool so it can report back the source of the
errors it founds, and can be invoked also in a --silent mode, when needed,
for backward compatibility. A missing flag has been added and the code
reformatted, as well as updates to the way the parameters are handled, for
consistency.
To minimize changes, it is assumed the regcomp error is of the right type
since we control the only caller, and is also assumed to affect both basic
and extended syntax (only basic is tested, but both behave the same in all
three affected platforms since they use the same function).

There are certain house-keeping tasks that need to be performed at
the very beginning of any Git program, and programs that are not
built-in commands had to do them exactly the same way as "git"
potty does. It was easy to make mistakes in one-off standalone
programs (like test helpers). A common "main()" function that
calls cmd_main() of individual program has been introduced to
make it harder to make mistakes.
* jk/common-main:
mingw: declare main()'s argv as const
common-main: call git_setup_gettext()
common-main: call restore_sigpipe_to_default()
common-main: call sanitize_stdfds()
common-main: call git_extract_argv0_path()
add an extra level of indirection to main()
"git grep -i" has been taught to fold case in non-ascii locales
correctly.
* nd/icase:
grep.c: reuse "icase" variable
diffcore-pickaxe: support case insensitive match on non-ascii
diffcore-pickaxe: Add regcomp_or_die()
grep/pcre: support utf-8
gettext: add is_utf8_locale()
grep/pcre: prepare locale-dependent tables for icase matching
grep: rewrite an if/else condition to avoid duplicate expression
grep/icase: avoid kwsset when -F is specified
grep/icase: avoid kwsset on literal non-ascii strings
test-regex: expose full regcomp() to the command line
test-regex: isolate the bug test code
grep: break down an "if" stmt in preparation for next changes
This keeps top dir a bit less crowded. And because these programs are
for testing purposes, it makes sense that they stay somewhere in t/
