Description:There is currently no way to read an entire string of text from a channel.  The "ast_recvchar" and "RECEIVE CHAR" functions read one character from a channel, then discard the rest of the string.  This functions fine for TDD MODE text and similar character-based text modes, but does not work for sending text from a local channel (app_sendtext) and such.  There should be a command to read an entire string at once from a channel.

****** ADDITIONAL INFORMATION ******

The attached patch creates a new function accessable from apps called "ast_recvtext" that returns the string, and also exposes this via AGI as "RECEIVE TEXT", the opposite of the existing "SEND TEXT" command.  The original "ast_recvchar" and "RECEIVE CHAR" functions are not modified, so as to not break applications that are currently using these functions.

Uploaded patch recvtext-20050613-2-sn.diff which obsoletes patch recvtext-20050613-sn.diff.  The new patch fixes multiple formatting issues, as well as adds a check for the return of malloc() to avoid dereferencing a null pointer if the malloc() fails.
