Andrey b49213e066 Connect to server only when client have pending data 
Currently we attach to server right after connection. This creates some
troubles especially in session pooling. With this commit we only attach
to server connection when at least one byte of client data arrived.

Dmitry Dolgov 4a09b5b7e9 Modifications to build on PG12 (#86) 
Build seems to fail with PostgreSQL 12 version, due to incompatibility
after [1], and required presence of libpgport (to expose pg_sprintf for
scram implementation).

To improve the situation, introduce couple of changes:

* Rely on pg_config to get lib/include directories
* Add libpgport.a into linking
* Provide different versions of pg_b64_decode/encode depending on
PG_VERSION_NUM

Andrey Borodin 8dff1aabef Wait for server connection on "too many connections" if pool_timeout!=0 
This reflects PgBouncer behavior on query_wait_timeout and should help
replace cascades of PgBouncers. Currently if wave of incoming
connections is coordinated casecade of PgBouncers will try smooth peak
with at least 2 seconds wait, while Odyssey just resest every
connection with is over role connection limit.
