These files are taken from PCRE2, Version 10.44.

The source files have been slightly modified in order to fit them into this
build system. The changes that were made are:

 - pcre2.h includes coda_pcre2_mangle.h to name mangle public symbols.

 - pcre2_internal.h and pcre2_config.c include coda_pcre2_config.h with CODA
   specific settings for PCRE2 (which would otherwise have been located in
   config.h).
