Fix unsafe use of a non-volatile variable in PG_TRY/PG_CATCH in AlterSystemSetConfigFile(). While at it, clean up a bundle of other infelicities and outright bugs, including corner-case-incorrect linked list manipulation, a poorly designed and worse documented parse-and-validate function (which even included some randomly chosen hard-wired substitutes for the specified elevel in one code path ... wtf?), direct use of open() instead of fd.c's facilities, inadequate checking of write()'s return value, and generally poorly written commentary.
