<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This change removes fixed size buffers in ODBC related code for reading in row data and func_odbc configuration. For func_odbc the configured queries are duplicated instead of being stored in a fixed size buffer. For dynamic realtime a thread local strings is enlarged as needed as row data is read in. For static realtime the maximum size of a configuration value is read in and buffer created accordingly.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Configured func_odbc within MySQL (via ODBC) using extconfig with a 3000 length query and configured it was read in completely. This used static realtime and func_odbc.
Configured chan_sip to use peers stored in MySQL (via ODBC) and stored very long values. Confirmed read in completely.
Also ran these scenarios under valgrind to confirm no memory insanity.</pre>
