Bundled pjproject: Make it easier to override options in config_site.h.

Bundled pjproject uses ./third-party/pjproject/patches/config_site.h to set
many pjproject build options like PJ_IOQUEUE_MAX_HANDLES, PJSIP_MAX_URL_SIZE,
etc. Editing that file however, causes the git tree to become dirty which
is inconvenient.  So...

* Updated the Asterisk configure scripts to pass the PJPROJECT_CFLAGS variable
down to the pjproject configure scripts.  See the UserNote below for details.

* Updated ./third-party/pjproject/patches/config_site.h to allow the following
options to be overridden:
PJ_MAX_HOSTNAME, PJSIP_MAX_URL_SIZE, PJ_IOQUEUE_MAX_HANDLES.
Other options in config_site.h are not overridable because they can have a
bad effect on the overall operation of pjproject.  This may be revisited in
the future.  Options not already set in config_site.h can still be set.

* Fixed an issue where if the Linux `epoll` facility is used (which it is by
default) the default PJ_IOQUEUE_MAX_HANDLES and PJSIP_MAX_TRANSPORTS were
being left at 1024 instead of being icnreased to 5000.

* The `pjproject show buildopts` CLI command previously only showed options from
the top level `PJ` pjproject layer but now also shows many from the `PJSIP`
layer.  Many of these, such as PJSIP_MAX_TRANSPORTS, can be set using
PJPROJECT_CFLAGS provided they're not already unconditionally set in
config_site.h.

* The `pjsip dump endpt` CLI command previously required that the pjproject
log level be already set to at least 3 or no output would be produced.  The
command now does that automatically then sets it back to whatever it was.
This isn't strictly related to this PR but was just nagging me.

UserNote: Bundled pjproject: It's now possible to override some of the pjproject
build options contained in ./third-party/pjproject/patches/config_site.h by
adding PJPROJECT_CFLAGS to your Asterisk ./configure command line.  For example:
`./configure ... PJPROJECT_CFLAGS='-DPJ_OPT1=8192 -DPJ_OPT2=512'`
Any option in config_site.h that's wrapped in a `#ifndef` block can be overridden
and many of the `PJSIP` options displayed by `pjproject show buildopts` can be
set.  WARNING: Adjusting these options without understanding their effect can
cripple your Asterisk instances.  You shouldn't adjust them unless you need
to solve a specific issue.

Resolves: #2011
