Make LLVM 15 happier by changing from K&R to ANSI prototypes

Untimely spring cleaning:
* Garbage collect useless hand-rolled lookup tables.
* Merge one-line helper functions into callers.
* Garbage collect obfuscating macros.
* Fix one format string error (%d used for u_int).
* Garbage collect setlocale(3) and <locale.h>.
* Garbage collect several unused constants.
* Minus 45 LOC, no functional change.

As noticed by tedu@, the lookup table "table" was used uninitialized.
But since it was only used as a pre-matching optimization and the real
string comparison is done further down the line, that bug probably did
not cause wrong results but merely ruined -i performance.

Code review triggered by a naive question from Jan Stary.
OK deraadt@ tedu@

keep the code that endian swaps, but remove the explanation that it's
for converting between freebsd and sunos.

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

userland reallocarray audit.

Replace malloc() and realloc() calls that may have integer overflow in the
multiplication of the size argument with reallocarray().

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

r?index -> strr?chr

Fix searching for shell quoting characters. From wosch@freebsd.

Blind update of wosch@FreeBSD's code:

optimized search algorithm
faster IO due mmap(2) [-m | -s]
better error check for damaged databases
support for databases in network byte order (SunOS/sparc)
optional case insensitve search [-i]
optional multiple databases
optional multiple pattern
new enviroment variable LOCATE_PATH for database(s)
[-S] print some statistic about the database
[-l number] limit output to number file names
[-c] suppress normal output; instead print a count of matching file names
fix prototypes/forward declarations/return type
