59c8d5dc27 top(1): fix err again
I am amazed at my ability to get a one-line error reporting line wrong
thrice.

bca1b45bb1 top(1): make error message happy
We don't use a "size" variable, so just don't report it.

8d0d26767b 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)

a9a99372d9 top(1): Use strsep instead of homegrown alternative
This replaces some complex, and not quite correct logic, with a more
common strsep pattern.

eae589f1ce top(1): another pass of cleanup
- 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

In fixing issues with uid > INT_MAX, I broke the uid without username
case. The latter is more important so return the old state.

While this came out of a conversation in IRC, it turn out that some
people don't like it. Since this was a courtesy feature, just remove it.

1d5b01e66e top(1): use greater warnings
One of the downsides of using numeric WARNS is that if we only have a
single type of issue we get no protection from other changes.  For
example, we got no warning for missing variable declaration, due to
the issues with "const".

For this utility, explicitly list out the warnings which are failing.
They should still be fixed, so only reduce them to warning instead of
error.

should just drop privs instead.

4fedcd4983 top(1): cleanup memory allocation and warnings

- Add additional const

51b29cb7b3 top: add -p option and p command to only show a single process
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.

937499dcb1 top(1): Display of TID when using 'H' flag
Some users prefer seeing the TID when viewing individual threads. This
makes sense as the PID will be the same for multiple entries. An attempt
was made to include both, but there is insufficient room. As such, using
the TID.

While here, rename the header variables to be more understandable.
