[Bruce Dubbs]

New minor version.

Release notes for 2.50 - 2021-05-24 12:05:16 -0700

Some new capsh features:

• --explain=cap_foo: describe what cap_foo does
• --suggest=phrase: search all the cap descriptions and describe those that match the phrase

• Add "keepcaps" module argument support to pam_cap.so
  • extend libcap to include cap_prctl() and cap_prctlw() functions to regain feature parity with Go "cap" package. These are only needed when linking against -lpsx for keepcaps POSIX semantics.
  • this likely requires substantial application changes to make Ambient capability support usable in general, but doing our part for the admin.

• Add a test case for recent kernel fix

• Go pragma fix for convenience functions in "cap" module

• Minor man documentation updates

• Minor build tree improvements (mostly for maintainer)
