FS-4859 regression
FS-4905
Various tweaks to spandsp, including starting to add some genuine ARM
optimisations.
Various tweaks to T.31 modem, prior to getting T.38 really working with T.31
don't block on db for fifo track_calls
FS-4928
FS-4928 doing 100 calls I found 7 million calls to toupper, this patch replaces it with an inline optimized one I found online.  Not sure it helps but maybe you can profile it again with latest.
add switch_toupper_max to uppercase a string 4 bytes at a time with new switch_toupper function
T.31 now gets somewhere in T.38 mode, although it still needs more work so
it functions properly in T.38 + ECM mode.

FS-4933 --resolve
FS-4931 --resolve ok, the binary also tries to make the dir but its probably failing from dropped perms.  probably if the freeswitch user had write perms in /var/run it would also work
