Brooks Davis ce5fa47cf0 share/mk: support for "single" group options
Support group options where 1 of n values will be selected (or a default
value will be used).  After processing, an OPT_FOO will be set to one
value from __FOO_OPTIONS for each FOO in __SINGLE_OPTIONS.  If the user
sets FOO that value will be used, otherwise __FOO_DEFAULT will be used.

Options that don't work an a particular system can be remapped to an
alternative using BROKEN_SINGLE_OPTIONS which can be set to a list of
3-tuples of the form:
	OPTION broken_value replacement_value

This is somewhat inspired by OPTIONS_SINGLE from ports, but the
structure is quite different with a per-option variable in the style of
MK_FOO={yes,no}.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
