Also remove the comment that indicated this "stupid subtraction" was done to pacify some ancient and unknown Cray compiler, and which has been there since the BSD 4.4 Lite Lib Sources were imported.

In the strfmon test in the test suite this caused the memmove to overflow the allocated buffer by one byte which CHERI caught. 2020-09-12T16:50:04Z Dimitry Andric dim@FreeBSD.org 2020-09-12T16:50:04Z urn:sha1:0428ad50794f234e056c0625673d1cf98c5a7ade Turn MALLOC_PRODUCTION into a regular src.conf(5) option For historical reasons, defining MALLOC_PRODUCTION in /etc/make.conf has been used to turn off potentially expensive debug checks and statistics gathering in the implementation of malloc(3). It seems more consistent to turn this into a regular src.conf(5) option, e.g. WITH_MALLOC_PRODUCTION / WITHOUT_MALLOC_PRODUCTION. This can then be toggled similar to any other source build option, and turned on or off by default for e.g. stable branches. Reviewed by: imp, #manpages Differential Revision: https://reviews.freebsd.org/D26337 MFC r365373: Follow-up r365371 by removing sentences which indicate the state of the MK_MALLOC_PRODUCTION option on -CURRENT. Also, for the sake of backwards compatibility, support the old way of enabling 'production malloc', e.g. by adding a define in make.conf(5). 2020-08-01T14:22:05Z Gordon Bergling gbe@FreeBSD.org 2020-08-01T14:22:05Z urn:sha1:43284b5b01b52a87c05f38bd266e1db7afc02746 These functions first appeared in the First Edition of Unix (or earlier in the pdp-7 version). Just claim 1st Edition for all this. The pdp-7 code is too fragmented at this point to extend history that far back. 2020-08-01T14:00:47Z Gordon Bergling gbe@FreeBSD.org 2020-08-01T14:00:47Z urn:sha1:1ee0e094d2439be1fde63240bcbe54fcb65e3bfc PR: 240259 Submitted by: gbe Reviewed by: bcr Approved by: bcr Obtained from: OpenBSD Differential Revision: https://reviews.freebsd.org/D24146 2020-05-24T10:16:47Z Benedict Reuschling bcr@FreeBSD.org 2020-05-24T10:16:47Z urn:sha1:3962fde9a455dd896343cbbdd010c8b086fbe877 Fix a typo: argments -> arguments PR: 243294 Submitted by: Igor Ostapenko MFC after: 5 days 2019-07-24T06:29:19Z Konstantin Belousov kib@FreeBSD.org 2019-07-24T06:29:19Z urn:sha1:0dbe011e2d05c74a7daf20e2e1bbf40ee7327923 bsearch.3: Improve the example
