Using the system libedit means that libedit will again make absolute
movements on certain kinds of terminals.  Older versions of libedit
without EL_PROMPT_ESC miscalculate the length of the prompt.
Combined, this results in the cursor ending up in the wrong place.

We knew this was a possibility when we moved to system libedit, and
we're OK with it.  We certainly lived without this fancy prompt
feature for a long time.

This change puts back in place detection of the terminal type when
EL_PROMPT_ESC isn't available.  On these older versions of libedit,
we'll only enable the fancy features when we know that libedit will
only make relative movements and not tickle the bug.

This partially reverts commit:

Newer versions of libedit provide an EL_REFRESH mechanism for
redrawing the prompt.  We had previously written our own code to
handle this.  In theory handing this over to libedit should be better.

Unfortunately when using EL_REFRESH the output of sofia siptrace isn't
showing up.  We're working on that, but for now we're just force own
our redrawing code to be used instead.

It wasn't supported, and we weren't building it by default as it was.

We consider mod_spidermonkey to be completely replaced by mod_v8 (and
more generally by mod_lua) at this point.  We've barely supported
mod_spidermonkey for years.  Everyone should stop using it.

We're keeping this around for awhile in case people are relying on C
extensions to mod_spidermonkey and need time to migrate.  This module
may or may not be part of a v1.4 release depending on whether we find
anyone cares.  It definitely will not be part of the next release
after v1.4.

Apparently CentOS 6 has only v3.6.20 of sqlite, so we'll accommodate
that barring evidence we shouldn't.  Please test and report back.

We've really only tested 3.8.3.1, so you might want to consider using
that.  We'll lower this down to 3.7.13 for Debian wheezy.  Please
test.

Autodetect whether the system libapr / libaprutil has our
necessary modifications and use it if it does.

This purges sqlite from our tree and requires it to be present on the
system for building and running FreeSWITCH.

mod_v8: Use parallel build by default. Use configure flag "--disable-parallel-build-v8" to disable it. It's disabled by default for Debian build scripts, since parallel build has some issues with cowbuilder.

This is currently breaking the build.  We'll get that fixed and add
mod_v8 back in after things slow down.
