- Prefer calloc over malloc. This is more predicable and we're not in a
performance sensitive context. [1]
- Remove bogus comment (obsolete from prior commit). [2]
- Remove void casts and type casts of NULL
- Remove redundant declaration of 'quit'
- Add additional const

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
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.

This corrects a warning issues by gcc9:
/srv/src/freebsd/head/usr.bin/top/machine.c:988:22: warning: '%5zu'
directive writing between 5 and 20 bytes into a
region of size 15 [-Wformat-overflow=]
sprintf(status, "?%5zu", state);
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.

This leaves at WARNS=6:
35 warnings in top.c
88 warnings in machine.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
- sprinkle const where possible
This leaves at WARNS=6:

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
