5e0a7a4450 Almost complete rewrite of the archive code (except for the Makefile parsing
part). Archive handling was broken at least since the move from BSD ar/ranlib
to GNU binutils because of the different archive format. This rewrite fixes
this by making make to carry around the defines for all formats (it supports)
so it can support all of them independent of the actually used one. The
supported formats are: traditional BSD (this seems to come from V7 at least,
short names only and __.SYMDEF), BSD4.4 (long names with #1/ and __.SYMDEF)
and SysV (extra name table and //). The only format not supported are broken
traditional archives where the member names are truncated to 15 characters.

Errors in the archive are not ignored anymore, but cause make to stop with
an error message. The command line option -A causes these errors to become
non-fatal. This is almost compatible with previous usage except for the
error message printed in any case.

Use a type-safe intrusive list for the archive cache.

ba467ce430 Make the structure for handling the input stack local to the parse
module. The only module accessing it (the current line number) was the
condition module, so pass the current line number as a function argument.
Centralize the pushing of new input sources into one function
ParsePushInput() and rename the function handling the popping from ParseEOF()
to ParsePopInput(). Make the entire thing a little bit clearer, by holding
the current input source in the top element of the stack instead of
using extra variables for this. Use a type-safe intrusive list for the
input stack.

f43eb6f83b Fix a bug introduced in a previous commit: ParseModifier() consumes
characters so it is not safe to move around code from
before it to after it. This should fix problems with building the
documentation.

72aa911a29 When doing the initial open of the proc via procfs, complain if we are
unable to open the /proc/pid/mem file.  Otherwise doing a truss on
a nonexistant pid makes us return success even though no such process
exists.

fd757c50f6 Support the L modifier for floating-point values as an extension.
When L is omitted, double precision is used, so printf(1) gives
reproducable results.  When L is specified, long double precision is
used, which may improve precision, depending on the machine.

2bcccc224c Don't skip the initialisation of tl->len when we hit an EOF immediately
after allocating a new buffer. This bug caused `tail -r < /dev/null'
to core dump when the `J' malloc option is set, and also affected
any other input that was an exact multiple of 128k.

0a5f326cd2 - Introduce an '-o' option which allows to match oldest of the matching
processes.
  This option can be also found in Solaris and Linux.
- Use timercmp(9) macro for timeval comparsion.
- Include time.h directly, don't depend on stat.h doing it for us.

d054f5d7cd - Introduce '-S' option which allows to match system processes (pgrep only).
- Rename IS_KERNPROC() macro to PSKIP() and extend its functionality.
  Now it'll skip calling process and system processes when -S is not given.
  As a side effect it fixes '-n' option. Before it was always matching
  calling process (because of missing 'if (kp->ki_pid == mypid)' check)
  and after that, calling process was ignored.
- When '-l' option is given and there are no arguments, use p_comm as an
  arguments list (this is helpful for kernel threads matching).
