* Fix parsing of ambiguous options, the whole loop must be processed.millert2013-06-081-15/+22

* Switch libc and libm to use strong aliases rather than weak aliasesmartynas2013-03-282-22/+4
| | | | | | | | | | | where appropriate. Among other things makes the symbols consistent across all architectures (notably where ldbl mantissa is 53 bits). While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there to trick lint into recording the right prototypes for aliased functions. Most of the work done at the awesome n2k13 hackathon. Agreed by kettenis@, guenther@, matthew@.

* Per POSIX, fix raise() and abort() to send the signal to the current thread.guenther2012-11-101-3/+5

* Add a new malloc option 'U' => "Free unmap" that does the guarding/djm2012-11-022-18/+36
| | | | | | | | | | | | unmapping of freed allocations without disabling chunk randomisation like the "Freeguard" ('F') option does. Make security 'S' option use 'U' and not 'F'. Rationale: guarding with no chunk randomisation is great for debugging use-after-free, but chunk randomisation offers better defence against "heap feng shui" style attacks that depend on carefully constructing a particular heap layout so we should leave this enabled when requesting security options.
* Make setenv(3) consistent with unsetenv(3), giving EINVAL if passedjeremy2012-09-232-20/+10

* make -column lists pretty again;jmc2011-09-031-3/+3
| | | | | | | | | | specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense.
* in column lists, enforce the following ordering:jmc2011-08-301-3/+3
| | | | | | | | | .Bl -column header1 header2 ... <Bl flags> mixing things up confuses mandoc, and adding flags in can screw up the list. this hopefully just makes things a bit safer (and more consistent). (one more bit of work left and all column lists should format how we want)
