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)

top(1): use a different command to toggle tid vs pid

- By popular demand, implement a different switch ("T") for toggling

- 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.

In fixing issues with uid > INT_MAX, I broke the uid without username

Allow to show only a single process specified by PID. This could

This changes previous behavior of calculating it at startup based on

This is done because:

(e.g., a new user is added after top starts running)
- on machines with many users this delays startup significantly
