Andrew Borodin 49624e473b Ticket #4450: support PCRE2 in the search engine.
* m4.include/ax_path_lib_pcre.m4: replace by recent version from GNU
Autoconf Archive.
  * m4.include/ax_check_pcre2.m4: get grom GNU Autoconf Archive.
  * m4.include/mc-check-search-type.m4: support both PCRE versions.
  * */*/Makefile.am: remove @CHECK_CFLAGS@ and @PCRE_LIBS@ ads they are
added via AX_PATH_LIB_PCRE and AX_CHECK_PCRE2.
  * lib/search.h, lib/search/: add support of PCRE2. Thanks broly <gagan@hotmail.com>
for the initial patch.
