Use literal instead of constant to fix 9.4 build 
PG_UINT32_MAX doesn't exist before 9.5. Missed this because I removed
my assert-enabled builds during packaging work.

Fixes #619

Amos Bird 107b926262 Eliminates the possibilities of counter overflows. 
This patch uses scanint8 instead of pg_atoi to make sure the affected
tuples counter never gets overflow.

Ensure router executor acquires proper shard lock 
Though Citus' Task struct has a shardId field, it doesn't have the same
semantics as the one previously used in pg_shard code. The analogous
field in the Citus Task is anchorShardId. I've also added an argument
check to the relevant locking function to catch future locking attempts
which pass an invalid argument.

First formatting attempt 
Skipped csql, ruleutils, readfuncs, and functions obviously copied from
PostgreSQL. Seeing how this looks, then continuing.

Rename GetConnection to address name conflict 
The postgres_fdw extension has an extern function with an identical
signature, which can cause problems when both extensions are loaded.
A simple rename can fix this for now (this is the only function with)
such a conflict.
