Summary:                    [patch] AGI returns bogus "510 Invalid or unknown
command"
Description: 
When res_agi.c reads from the AGI stream, it incorrectly calculates the
number of free bytes remaining in the read buffer. In certain circumstances
(such as repeated EAGAIN errors from fgets), this causes it to incorrectly
interpret the buffer as full. That then confuses the code interpreting the
command, leading to a bogus "510 invalid or unknown command" error being
returned.
