0x12 Environment Variables (arbitrary number of C strings)
Is written at session start. Contains the environment variables and their values
as NAME=value pairs, each pair is terminated by a null byte (0x00). Since
variable names may not contain the = character and neither variables names
nor the values may include a null byte, the list needs no special escaping.

Defines:
chunk12, used in chunk 34c.
Uses chunkwd 21, chunkwf 22d, and chunkwh 22d.
0x13 Locale Settings (seven C strings)
Is written at session start. Contains the string values of several locale settings,
namely LC ALL, LC COLLATE, LC CTYPE, LC MESSAGES, LC MONETARY, LC NUMERIC
and LC TIME, in that order, each terminated by a null byte.
