Replace some strtok() with strsep()
strtok() considers adjacent delimiters to be one delimiter, which is
arguably the wrong behavior in some cases. Replace with strsep(),
which has the right behavior: Adjacent delimiters create an empty
token.
Affected by this are parsing of:
- Stored SCRAM secrets
("SCRAM-SHA-256$<iterations>:<salt>$<storedkey>:<serverkey>")
- ICU collation attributes
("und@colStrength=primary;colCaseLevel=yes") for ICU older than
version 54
- PG_COLORS environment variable
("error=01;31:warning=01;35:note=01;36:locus=01")
- pg_regress command-line options with comma-separated list arguments
(--dbname, --create-role) (currently only used pg_regress_ecpg)
