The current header formatting is a giant format string that changes
global state during the format process.
Make the following changes:
- use sbuf to build up the header rather than use the above
pseudo-dynamic one
- Change name length to 10
- Reduce size of RES and SIZE by making humanize more aggressive
- Restore a version number line to the copyright. This may be required
by the copyright (and may not be; its unclear)
This is also a pre-req to implementing TOPCOLOR from newer versions of
top(1)

- By popular demand, implement a different switch ("T") for toggling
between thread id and process id.
- Add an assert that the size of command chars is as expected.
- Also clean up some messiness I found when implementing this.
- Further document the new flag.

- 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)
- avoid the need to call a function to get size of known array. I'll
likely re-arrange some of the indirect in a later to avoid the magic
constants.
- use correct type
- add const
- replace caddr_t with void*. This corrects an alignment warning.
- remove duplicated include from immediately prior commit
Under base clang we're now down to:
- 3 warning in top.c, 1 warning in mahcine.c, 4 warning in display.c,
- 1 warning in utils.c
Tested with base clang, gcc7, gcc9, base gcc (mips)
- Add const where helpful
- add missing 'static' for file-local functions
- use nitems where possible
- convert manual abort() to assert
- use strndup instead of homegrown version
Tested with clang, gcc7, and gcc9
In fixing issues with uid > INT_MAX, I broke the uid without username
case. The latter is more important so return the old state.
Discussed with: allanjude
Allow to show only a single process specified by PID. This could
be done either by running top like 'top -p PID' or using the 'p' command
inside top.

- 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
- 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"
- Replace caddr_t with "void *". This reduces
the number of warnings at WARNS=6
- use "static" where possible

This leaves at WARNS=6:
35 warnings in top.c
72 warnings in machine.c
5 warnings in commands.c

or "cast-qual"
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

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.
