Fix inappropriate uses of atol()
Some code using atol() would not work correctly if sizeof(long)==4:
- src/bin/pg_basebackup/pg_basebackup.c: Would miscount size of a
tablespace over 2 TB.
- src/bin/pg_basebackup/streamutil.c: Would truncate a timeline ID
beyond INT32_MAX.
- src/bin/pg_rewind/libpq_source.c: Would miscount size of files
larger than 2 GB (but this currently cannot happen).
Replace these with atoll().
In one case, the use of atol() did not result in incorrect behavior
but seems inconsistent with related code:
- src/interfaces/ecpg/ecpglib/execute.c: Gratuitous, since it
processes a value from pg_type.typlen, which is int16.
Replace this with atoi().
