Add more features to the one remaining to handle the job:
+ signed quantity.
# alternate format
- left padding
* read width as next arg.
n numeric in (argument specified) default radix.
Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.
The warnings from gcc may become more wrong and intolerable because
of this.
Warning: I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

the loop that invokes the static constructors. That makes it safe
to link c++rt0.o into any shared library, even one that does not
have any static constructors. Formerly, doing that would cause a
bus error. If the library has no static constructors, __CTOR_LIST__
comes out as a simple 4-byte COMMON region, and it does not have
the usual NULL word that terminates the list of constructors. This
caused the old code to "call" a garbage address via the non-existent
entry __CTOR_LIST__[1].
The analogous code that invokes the static destructors was already safe.
This change is fully backward-compatible.

route.c: look up the netname as-is first before the shifted name. this
makes a big speed difference, as the lookups are generally local
DNS. The shifted names can be very wrong (there is still guessing
and fudging involved) and usually go remote, taking a long time
to fail. If you have the RFC reccomended netnames in your reverse
lookups, this is even faster still.
main.c: dont do a sethostent(1) - this is causing the resolver to use a
VC (tcp) connection to the resolver, which has more overheads and
is slower than the default UDP case. This once made sense when
everything was based on text host tables.
the standard macro dbtob(). The non-B_PAGING case now works well enough
to run newfs on a 32GB virtual drive.
Fixed numerous bogus variable types and one overflowing multiplication
in the B_PAGING case of vnstrategy(). Swapping to virtual drives larger
than 2GB might work now.
This fixes PR943.
ffs/ffs_vfsops.c:
ffs_statfs() multiplied by (100 - minfree) as part of calculating the
minfree percentage (complemented in 100%), so with the standard minfree
of 8, it was broken for file systems of size >= 1TB/92 = 11GB. Use the
standard freespace() macro instead. This also fixes a rounding bug (the
"Avail" count was sometimes 1 too small).
ffs/* (not fixed):
The freespace() macro multiplies by minfree, so with the standard
minfree of 8, it is broken for file systems of size >= 1TB/8 = 128GB.
This bug is more serious since it affects block allocation.
ffs/ffs_alloc.c (not fixed):
Ordinary users are sometimes allowed to allocate 1 (partial) block
too many so that the "Avail" count goes negative. E.g., if there is
1 fragment available and the file is fairly large, one more full
block is allocated.
df/df.c:
ufs_df() used/uses essentially the same code as ffs_statfs(), so it
had/has the same bugs.
ufs_df() gratuitously replaced "Avail" counts of < 0 by 0, so it
gave different results for non-mounted file systems in this case.
It addresses a number of problems that were present in earlier
versions.
The calls to the "init" and "fini" functions of shared libraries
have been reordered, so that they are called in a strictly nested
fashion, as is required for C++ constructors and destructors. In
addition, the "init" functions are called in better order relative
to each other. That makes the system more tolerant of C++ programs
which depend on a library's being initialized before its clients.
The dynamic linker is now more tolerant of shared libraries in
which dependencies on other shared libraries are incompletely
recorded.
Cleanup in the event of errors has been improved throughout the
dynamic linker. A number of memory leaks were eliminated.
The warning message for a shared library whose minor version number
is too old has been clarified.
The code dealing with the "ld.so.hints" file has been cleaned up.
A bug that caused the hints file to be unmapped incompletely has
been fixed. A different bug that could potentially cause the hints
file to be mapped on top of a loaded object has been fixed.
The code that searches for shared libraries has been cleaned up.
The searching is now more compatible with that done by SunOS and
SVR4. Also, some unnecessary and useless searches of both the
hints file and library directories have been eliminated.

This program does what the old one did, PLUS:
- Supports parallel jobs (like the SunOS yppush)
- Does everything in one proces instead of fork()ing off
children processes as callback listeners (this is done
using async socket I/O).
- Can be used to transmit maps to user-specified hosts.
- Has a much more verbose verbose option.
- Reuses existing code from ypserv and ypxfr.
- Uses some rpcgen-erated code as well.
- Isn't fattening. :)
Note that this is going in /usr/sbin rather than /usr/bin like
the old one. yppush is an administrative command it it's anything.
