Retire src/backend/utils/misc/check_guc

Browse Source 
This script has existed for a long time, and attempting to run it today
causes a lot of false positives as an effect of GUCs added in the last
couple of years.  An equivalent, automatically-run and cross-platform
solution is available in the TAP test introduced in b0a55f4.  So, let it
go.

## currently, this script makes a lot of assumptions:
## in postgresql.conf.sample:
## 1) the valid config settings may be preceded by a '#', but NOT '# '
## (we use this to skip comments)
## 2) the valid config settings will be followed immediately by ' ='
## (at least one space preceding the '=')
## in guc.c:
## 3) the options have PGC_ on the same line as the option
## 4) the options have '{' on the same line as the option
## Problems
## 1) Don't know what to do with TRANSACTION ISOLATION LEVEL
## if an option is valid but shows up in only one file (guc.c but not
## postgresql.conf.sample), it should be listed here so that it
## can be ignored
