Hello Joshua Colp, Kevin Harwell, Friendly Automation, 

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

media_cache: Don't lock when curl the remote file

When playing a remote sound file, which is not in cache, first we need to download
it with ast_bucket_file_retrieve.

This can take a while if the remote host is slow. The current CURL timeout is
180secs, so in extreme situations, it can take 3 minutes to return.

Because ast_media_cache_retrieve has a lock on all function, while we are waiting
for the delayed download, Asterisk is not able to play any more files, even the
files already cached locally.

ASTERISK-29544 #close
