Subject: MINOR: connection: add conn_new() / conn_free()
X-Git-Tag: v1.5-dev20~102

MINOR: connection: add conn_new() / conn_free()

conn_new() will be a more convenient way of allocating and initializing
a connection. It calls pool_alloc2() and conn_init() upon success.

conn_free() is just a pool_free2() but is provided for symmetry with
conn_new().
