Update extensions.lua.sample with naming conflict guidance.

The sample extensions.lua was causing pbx_lua to fail to load when parsing
'app.goto("default", "s", 1)' because in Lua 5.2, 'goto' is now a reserved
word.  This patch adds guidance to extensions.lua.sample and changed
'app.goto("default", "s", 1)' to 'app.['goto']("default", "s", 1)'.

Remove the problematic and unneeded AST_MODFLAG_GLOBAL_SYMBOLS from pbx_lua.c

AST_MODFLAG_GLOBAL_SYMBOLS was causing the module to be incorrectly loaded
before pbx_config.  pbx_config was therefore blowing away contexts that were
created by pbx_lua.  With AST_MODFLAG_DEFAULT the load order is now correct
and contexs are being properly merged.  AST_MODFLAG_GLOBAL_SYMBOLS was not
needed anyway since no other modules needed its global symbols that early.

build: Allow autoconf/ast_ext_tool_check to handle cross-compiling better.

ast_ext_tool_check.m4 isn't handling cases where a path to a package is
provided (E.G. --with-mysqlclient=/some/sysroot) and the package has a config
tool (E.G. mysql_config) and the package has its own subdirectories in include
or lib.  For example, mysql's libraries are in ${MYSQLCLIENT_DIR}/usr/lib/mysql
but ast_ext_tool_check sets MYSQLCLIENT_LIB to ${MYSQLCLIENT_DIR}/usr/lib.
libxml2 has the same problem with its includes.  They're in 
${LIBXML2_DIR}/usr/include/libxml2 not directly in ${LIBXML2_DIR}/usr/include.
Both cause configure to fail and there are others in the same boat.

The problem is caused by logic in ast_ext_tool_check that overrides the result
of the config tool's --cflags and --libs options if package_DIR is set.

This patch prepends package_DIR (if specified) to the -L and -I results from
the package's config tool instead of overriding them.

A regenerated ./configure and include/asterisk/autoconfig.h.in are included
but can be regenerated by running ./bootstrap.sh at any time.

build:  Turn FORTIFY_SOURCE off if DONT_OPTIMIZE is set.

AST_FORTIFY_SOURCE is automatically set in ./Makefile even if DONT_OPTIMIZE
is set in menuselect.  This causes gcc to complain that _FORTIFY_SOURCE
requires optimization and the build will fail.  You can specify
"make AST_FORTIFY_SOURCE=''" but I always forget.

This patch moves the set of AST_FORTIFY_SOURCE to Makefile.rules and only
sets it if DONT_OPTIMIZE is "no".  The move is necessary because the
top-level Makefile doesn't include menuselect.makeopts.

This doesn't solve the entire problem however because res_config_mysql
seems to force _FORTIFY_SOURCE so res_config_mysql has to be disabled
for now if DONT_OPTIMIZE is set.

main/features - documentation - reformat examples and options in features.conf.sample to show clearly which options apply in which section

The features.conf sample can be a bit confusing about what parking options can be set only in the general context, or both in the general context (for the default parking lot) and in other parking lot contexts. A bug was filed due to confusion and a little googling will show lots of other confused users.

Despite some comments on the individual options, it still reads in a confusing way. In this patch I separate out those options with some headings in to attempt a better layout. I went ahead and modified other headings in the file, or added them to facilitate better visual scanning.
