mod_v8: Added shell script used to fetch a specific version of V8 from git, and package it into tarballs

FS-6095 --resolve modified to protect against memory leak and make it more consistant with other modules

Check if stdint has been included before trying to declare int variants. Needed for mod_v8 build in Windows

Minor modifications on the original patch to use ftdm_hunting_direction_t
everywhere instead of ftdm_direction_t or int

Patched-by: Marc Olivier Chouinard

add legacy subdir for mods with 5.1 edition of mod_lua, change languages/mod_lua to legacy/languages/mod_lua in modules.conf to use older lua mod

This is intended to make it easier to describe to users on JIRA how
they should test build patches in a standardized manner and how to
collect a full build log that includes the exact git commit they are
building.

Previously we were including the output of `apr-1-config/apu-1-config
--libs` into CORE_LIBS.  This seemed sensible as CORE_LIBS is added in
the right places to various _LDADD and _LIBADD variables.  However we
also use the value of CORE_LIBS as dependencies in the makefile.
Astonishingly this doesn't seem to cause any issues on most
platforms (or we would have noticed sooner), but it does break things
on Mac.
