cbd9f9e6b7 * Use ENTERI() and RETURNI() to toggle the rounding precision if
necessary, so that cosl(), sinl() and tanl() work on i386 even
  for naive callers.

33134d2526 * Make STRICT_ALIGN() work for doubles as well as for floats. This
only affects i386.  The double case was intentionally left broken
  as an optimization, but we are getting closer to supporting
  applications and/or kernels that change the (FreeBSD i386) default
  rounding precision from FP_PD to FP_PE and never change it back,
  and this requires the STRICT_ALIGN()s that were added to support
  FP_PE to actually work in all precisions.

* Remove an extraneous semicolon at the end of a macro that was
  supposed to be function-like.

3a2b0e2811 Restore handling of the third argument (id) of hid_start_parse(), same as
it is done in NetBSD/OpenBSD, and as it was here before r205728.

I personally think this API or its implementation is incorrect, as it is not
correct to filter collections based on report ID, as they are orthogonal
in general case, but I see no harm from supporting this feature.

87d02085ac Avoid mapping ENOENT to ENOTDIR for non-existent path components.
The ENOTDIR mapping was introduced in r235266 for kern/128933 based on
an interpretation of the somewhat ambiguous language in the POSIX realpath
specification.  The interpretation is inconsistent with Solaris and Linux,
a regression from 9.0, and does not appear to be permitted by the
description of ENOTDIR:

     20 ENOTDIR Not a directory.  A component of the specified pathname
             existed, but it was not a directory, when a directory was
             expected.

bd7319c0d8 libc/amd64: Do not export .cerror.
For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit
in the FBSDprivate_1.0 version. It looks like there is no reason for this
since it is not used from other libraries. Given that it cannot be accessed
from C and its strange calling convention, it is rather unlikely that other
things rely on it. Perhaps it is from a time when symbols could not be
hidden.

Most of the amd64 assembler code jumps to .cerror using the GOT. It can jump
to it directly now, as in non-PIC mode.

There are also some minor size optimizations to instructions but they yield
virtually no benefit in the size of libc.so.7 due to padding.

a78b4512de libc/i386: Do not export .cerror.
For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit
in the FBSDprivate_1.0 version. It looks like there is no reason for this
since it is not used from other libraries. Given that it cannot be accessed
from C and its strange calling convention, it is rather unlikely that other
things rely on it. Perhaps it is from a time when symbols could not be
hidden.

Not exporting .cerror causes it to be jumped to directly instead of via the
PLT.

This change also takes advantage of .cerror's new status by not saving and
loading %ebx before jumping to it. (Therefore, .cerror now saves and loads
%ebx itself.) Where there was a conditional jump to a jump to .cerror, the
conditional jump has been changed to jump to .cerror directly (many modern
CPUs don't do static prediction and in any case it is not much of a benefit
anyway).

This change makes libc.so.7 a few kilobytes smaller.

02dcf28b58 Rework all non-contributed files that use `struct timezone'.
This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

	int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

libtirpc: set r_netid and r_owner in __rpcb_findaddr_timed

These fields in the rpcbind GETADDR call are being passed uninitialized
to CLNT_CALL. In the case of x86_64 at least, this usually leads to a
segfault. On x86, it sometimes causes segfaults and other times causes
garbage to be sent on the wire.

rpcbind generally ignores the r_owner field for calls that come in over
the wire, so it really doesn't matter what we send in that slot. We just
need to send something. The reference implementation from Sun seems to
send a blank string. Have ours follow suit.

libtirpc: be sure to free cl_netid and cl_tp
