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)

- initialize all maybe uninitialized vars with bogus values. This shuts
up the compiler, and causes crashes if it changes later.
- mark noreturn as noreturn
- removed unused macro
- handle x_procstate as runtime rather than pre-processor
- avoid using void functions in condtionals
Tested with clang, gcc 7, gcc 9
- remove WARNS?=6. It is default
- we no longer have cast-qual problems
- remove unused macros
- remove unneeded casts
- add include guard for loadavg.h
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.
Tested with: clang base (amd64, i386), gcc6, gcc7, gcc9, gcc base (mips)
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.
Pointyhat to: me
- 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
72 warnings in machine.c
5 warnings in commands.c
all of which are either "incompatible-pointer-types-discards-qualifiers"
or "cast-qual"
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.

Prefer ${SRCTOP}/foo over ${.CURDIR}/../../foo and ${SRCTOP}/usr.bin/foo
over ${.CURDIR}/../foo for paths in Makefiles.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

contrib/top/top.local.H to contrib/top/top.local.hs.
This fixes a build breakage when src is on a case-
insensitive file system -- we never properly create
top.x nor top.local.h. Change the makefile accordingly.

contains a sigdec[] vector of structures, but the generated output is
missing braces around the initializer of each struct, which
triggers warnings in WARNS=3:
src/usr.bin/top/sigdesc.h:10: warning: missing braces around initializer
src/usr.bin/top/sigdesc.h:10: warning: (near initialization for `sigdesc[0]')
* Fix the sigconv.awk script to generate a header with initializers
which look better.
* Add rules to usr.bin/top/Makefile that rebuilds a new sigconv.h
header which matches the correct signal set from the build-time
version of `${DESTDIR}/usr/include/signal.h' (so sigconv.h doesn't
get stale once changes are made to the header).
* Remove the old sigconv.h header, now that it is autoupdated at
build time.
* Various Makefile style fixes (the committed Makefile was kindly
submitted by Ruslan):
- Reorder .PATH, PROG, SRCS and CFLAGS to match style.Makefile(5)
- Split off the generated sources (sigdesc.h top.local.h) in an
SRCS+= line of their own.
- Add entries to CLEANFILES near the rules that generate the
respective files.
- Move the explicit rule which builds top.1 after the implicit
rules which generate its dependencies.
