035e5608d5 Fixed cleaning up after malloc failure, which was broken by Lite2. 
We don't use socketpair(), so don't #include <sys/socket.h>.

Restored some gcc-quieting parentheses that were lost in the Lite2 merge.

Document that popen() can now create bidirectional pipes and handles.
Note that this needs to be updated since we have a native bidirectional
pipe and don't use socketpair() here.

e836e480dc Fixed handling of input failure by the scanf family. 
- 0 was returned instead of EOF when an input failure occured while
  skipping white-space after 0 assignments.  This fixes PR2606.  The
  diagnosis in PR2606 is wrong.
- EOF was returned instead of 0 when an input failure occurred after
  zero assignments and nonzero suppressed assignments.
- EOF was spelled -1.

59e5dcc34f Use .Sq Li \&\e0 rather than NUL to describe the character with no bits 
set, as suggested by Garrett Wollman.   This is more consistant with how
things like strncpy are done, as well as harder to confuse NUL and NULL.

cdd42308ce Enabled the Lite2 getvfsbyname(). It's actually named new_getvfsbyname() 
for now so that we don't lose library compatibility.  Applications should
define _NEW_VFSCONF and use getvfsbyname() instead of new_getvfsbyname()
if they want the new vfsconf interface.  Parts of the old interface
(enough to load vfs modules, I hope) are still available.

487ddb8fa4 Compute (1 - x^2) as ((1 - x) * (1 + x)) instead of as (1 - x * x) to 
avoid easily avoidable loss of precision when |x| is nearly 1.

Extended (64-bit) precision only moves the meaning of "nearly" here.

This probably could be done better by splitting up the range into
|x| <= 0.5 and |x| > 0.5 like the C version.  However, ucbtest
does't report any errors in this version.  Perhaps the C version
should be used anyway.  It's only 25% slower now on a P5, provided
the C version of sqrt() isn't used, and the C version could be
optimized better.

dab159e3d6 Select between the generic math functions and the i387-specific ones 
at runtime.

etc/make.conf:
Nuked HAVE_FPU option.

lib/msun/Makefile:
Always build the i387 objects.  Copy the i387 source files at build
time so that the i387 objects have different names.  This is simpler
than renaming the files in the cvs repository or repeating half of
bsd.lib.mk to add explicit rules.

lib/msun/src/*.c:
Renamed all functions that have an i387-specific version by adding
`__generic_' to their names.

lib/msun/src/get_hw_float.c:
New file for getting machdep.hw_float from the kernel.

sys/i386/include/asmacros.h:
Abuse the ENTRY() macro to generate jump vectors and associated code.
This works much like PIC PLT dynamic initialization.  The PIC case is
messy.  The old i387 entry points are renamed.  Renaming is easier
here because the names are given by macro expansions.

799e5901b3 Use the C library version of log10() instead of the inaccurate formula 
log10(x) = log10e * log(x).  The formula would work if the RHS were
evaluated in extended precision with an extended precision log().
This actually happened with the i387 log() because it returns excess
precision.

ec7d3a3282 Disabled the i387 version if log1p(). It just evaluates log(1 + x). 
This defeats the point of log1p().  ucbtest reports errors of +-5e+15
ULPs.  A correct version would use the i387 fyl2xp1 instruction for
small x and maybe scale to small x.  The C version does the scaling
reasonably efficiently, and fyl2px1 is slow (at least on P5s), so not
much is lost by always using the C version (only 25% for small x even
with the broken i387 version; 50% for large x).
