10550f0b0a top(1): increase number of columns for memory
The original intention was 4 columns but with a usable a result. In
practice this was not the case. Increase the number of columns to 5
until humanize_number learns alternative ways of presenting the number.

7452122499 top(1): rollback r335836
Encoding-specific processing introduced in r335836 is not recommended.
And doing getenv("LANG") and assuming an encoding based on it is a
very bad practice to internationalize software.

51c834c490 top(1): reimplement header formatting as sbuf
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)

f764243341 top(1): remove unneeded logic
- remove __pure annotations I added earlier for some functions. One
writes to the the arguments as "out" pointers. The
other reads from an array, which while const within the function might
be mutated externally.
- total_change is modified to be at 1, if previously 0, so no if check
is needed.

I had changed this from a for loop to a memset during an earlier

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)
