Rewrite SQL configuration support.
Multiple configurations can be provided, by calling dbrw.config from
branches of a conditional VCL statement. The only requirement is that
exactly one dbrw.config is executed within a single HTTP session. This
allows the user to select rewrite data from various databases depending
on some conditions.
Open SQL connections are stored in a pool and reused as needed. So far
no limit on the number of connections is imposed. This is a TODO.
Connections remain open during the lifetime of the module (i.e. for as
long as varnish is not restarted).
* src/dbrw.h (dbrw_config): New members: param_str, magic and list.
(dbrw_connection): New members: magic, busy, list.
* src/vmod_dbrw.c (dbrw_connection_get)
(dbrw_connection_release): New functions.
(dbrw_event): Install atexit function.
(vmod_config): Keep a pool of configurations.
(dbrw_sethdr) [VARNISHVERSION]: Remove leftover code.
(vmod_rewrite): Rewrite.
* src/vmod_dbrw.vcc (config, rewrite): Mark as PRIV_TASK.
* doc/vmod-dbrw.3: Update docs.
* doc/vmod-dbrw.texi: Update docs.
* configure.ac: Raise version number
