[DTrace-devel] [PATCH 4/7] Increase the maximum size of strstab

[Kris Van Hees]

The strtab size was limited in the legacy version to 0x7fff.  This
was generally sufficient because of how the strtab was implemented.
Now that all strings used in a probe program are stored in a single
strtab (incl. probe description names), a higher limit is needed.

All string offsets (and strtab size calculations) are using ssize_t,
so we use SSIZE_MAX as the upper limit.
