* commit 'f4a6e6e3':
  Remove the FreeSWITCH core handler for SIG_CHLD.

FS-7066 FS-7253 FS-7231 #comment remove TFD_TIMER_ABSTIME as it seems to cause some load issues on some machines

This does not appear to be needed any longer, and while this is in
place a dependent library that tries to start a child process will
hang waiting on the SIG_CHLD signal that the FreeSWITCH core 'ate'.

FS-7250 #resolve

FS-7164 [mod_rayo] support input grammar URL for MRCP only.  Mixing URL and embedded grammars in same input request (but in different grammar elements) should work

1. Switch from mm-dd-yyyy to dd-mm-yyyy
2. Insert "de" (Spanish for "of") preposition.
3. Document this new voice recording "of.wav".

As reported in FS-7279.

* commit '299b313b':
  FS-7269 : Add error logs in exec_user_method() when exception occurs.

In exec_user_method() report ERROR LOG to console in cases exceptions occurs,
like if any of class/method/userMethod->arg is null or for any reason which
sets status to SWITCH_STATUS_FALSE because that prevents loading mod_java and
users don't have clue why it is failing to load.

With this patch error logs can tell why method failed to execute.
