mod_sofia's parameter shutdown-on-fail now accepts the value
"reincarnate-now".  This will cause the switch to exit immediately
with a non-zero exit code so that the supervisor can recover the
switch.  For this to work you have to pass in -reincarnate or
-reincarnate-reexec to freeswitch.

This is the result of auditing each mod_sofia profile parameter to
ensure that it can be unset or reset after being set.  One use-case
for this being done correctly is so a later parameter in a
configuration file can reliably override an earlier one, which is
useful for setups with layered include files.

We were leaking the string values of apply-candidate-acl parameters.

In UNIX, text files by definition end with a newline.

This commit allows you to set a `log-file` string parameter in a
format_cdr profile.  This string is a template that may (and should!)
contain variables.  This template will be expanded and used as the
file name of the CDR to be written.  This parameter should contain
only the template for the file name itself; the path is relative to
the `log-dir`.

Previously if send-display-update was set to false we would also
remove UPDATE from our Allow: headers.  This is unnecessary.  The
UPDATE message is useful in SIP transactions even if we're not sending
display updates.

With this commit, we add a new boolean profile flag, allow-update.  If
set to true we'll send Allow: UPDATE.  If set to false, we will not.
If there is a conflict with another setting that requires UPDATE
support, the allow-update parameter will win and a warning will be
printed.
