MFC r308432, r308657: Capsicumize some trivial stdio programs

2018-04-13T03:30:10Z

r308432: Capsicumize some trivial stdio programs Trivially capsicumize some simple programs that just interact with stdio. This list of programs uses 'pledge("stdio")' in OpenBSD. r308657: fold(1): Revert incorrect r308432 As Jean-Sébastien notes, fold(1) requires handling argv-supplied files. That will require a slightly more sophisticated approach.

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

understand which code paths aren't possible. This commit eliminates 117 false positive bug reports of the form "allocate memory; error out if pointer is NULL; use pointer".

- Check and report write(2) errors.

- Issue a single writev(2) call instead of multiple write(2)s. This change improves the inefficiencies introduced when echo went on an stdio diet. The following figures are for echoing 1000 arguments. original stdio-based echo: 0.01 real 0.01 user 0.00 sys before: 0.05 real 0.00 user 0.04 sys after: 0.01 real 0.00 user 0.00 sys

Put echo on a diet, removing unnecessary use of stdio and getopt.
