8876d70038 top(1): include what you use
- Change headers to more closely match what we use
- use more standard functions instead of bzero, bcmp, bcopy
- Add myself to authors.

Tested with: base clang (amd64), gcc 9 (amd64), base clang (i386), base
gcc (mips)

6458a7dc63 top(1): partial revert of r334517
In fixing issues with uid > INT_MAX, I broke the uid without username
case. The latter is more important so return the old state.

72a0a627b4 top(1): ansify, style(9). and nits
- Prefer using ansi prototypes rather than C prototypes
- Keep type on separate line from name of function
- Try to keep things const where possible. This will help get to WARNS=6
- switch to "bool" where it makes sense

7ff9451fb2 top(1): fix build
Remove 'top.local.hs'. This was not noticed since
/srv/obj/fbsd/srv/src/freebsd/svn/head/amd64.amd64/usr.bin/top/top.local.h
existed locally on my machine despite "make clean". Only fully removing
the objdir allowed me to observe the error directly.

23c360e23f top(1): modernize a bit; reduce warnings
- Replace caddr_t with "void *". This reduces
the number of warnings at WARNS=6
- use "static" where possible
- sprinkle const where possible

This leaves at WARNS=6:
35 warnings in top.c
88 warnings in machine.c
7 warnings in commands.c

all of which are either "incompatible-pointer-types-discards-qualifiers"
or "cast-qual"

4e4f3a8d0c top(1): pull configuration directly into header files
This sets configuration variables directly in the various header files,
avoiding the need to have special logic in our Makefile to build the
header.

540c3db568 top(1): set max username length based on system constant
This changes previous behavior of calculating it at startup based on
the current max username length.

This is done because:
- it is in theory possible for the max length to change at run-time
  (e.g., a new user is added after top starts running)
- on machines with many users this delays startup significantly

aac06c5109 top(1): remove use of 'register' keyword
This keyword is meaningless is obscures future diffs that help clear up
warnings in top.

2ddbba1d82 top(1): Migrate top to usr.bin
We've been maintaining top(1) for a long time, and the upstream
hasn't existed/been used in similarly as long. Make it clear that we own
top(1)

Tested with 'make universe'. Everything passed except MIPS which failed
for unrelated reasons. Install also tested for amd64.
