capability v0.4.0

Added

• New separate API for ambient ([GetAmbient], [SetAmbient], [ResetAmbient]) and bound ([GetBound], [DropBound]) capabilities, modelled after libcap. (#176)

Fixed

• [Apply] now returns an error if called for non-zero pid. Before this change, it could silently change some capabilities of the current process, instead of the one identified by the pid. (#168, #174)
• Fixed tests that change capabilities to be run in a separate process. (#173)
• Other improvements in tests. (#169, #170)

Changed

• Use raw syscalls (which are slightly faster). (#176)
• Most tests are now limited to testing the public API of the package. (#162)
• Simplify parsing /proc/pid/status, add a test case. (#162)
• Optimize the number of syscall to set ambient capabilities in Apply by clearing them first; add a test case. (#163, #164)
• Better documentation for [Apply], [NewFile], [NewFile2], [NewPid], [NewPid2]. (#175)
