18ae4fcc47 If telldir() is called immediately after a call to seekdir(), POSIX
requires the return value of telldir() to equal the value passed to
seekdir().  The current seekdir code with SINGLEUSE enabled breaks
this case as each call to telldir() allocates a new cookie.  Instead,
remove the SINGLEUSE code and change telldir() to look for an existing
cookie for the directory's current location rather than always creating
a new cookie.

86727cc9c6 Avoid possible cast degradation.
For consistency with r268985 for fputs.c, assign iov_len
first, avoiding the cast to uio_resid (int in stdio)
from degrading the value.

We currently don't support lengths higher than INT_MAX so
this change is little more than cosmetic.

e19f362e28 Fix hdestroy() compliance issue.
The hcreate(3) implementation and related functions we inherited
from NetBSD used to free() the key value, something that is not
supported by the standard implementation.

This would cause a segmentation fault when attempting to run
the examples from the opengroup and linux manpages.  NetBSD
has added non-standard calls to provide the previous
behaviour but hdestroy is not very commonly used so at this
time it seems excessive to bring those to FreeBSD.

Bump the __FreeBSD_version as this is an ABI change.

677a88cec2 Add dl_unwind_find_exidx() for ARM EABI, required for C++ exception
handling.  For statically linked apps this uses the __exidx_start/end
symbols set up by the linker.  For dynamically linked apps it finds the
shared object that contains the given address and returns the location and
size of the exidx section in that shared object.

The dl_unwind_find_exidx() name is used by other BSD projects and Android,
and is mentioned in clang 3.5 comments as "the BSD interface" for finding
exidx data.  GCC (in libgcc_s) expects the exact same API and functionality
to be provided by a function named __gnu_Unwind_Find_exidx(), so we provide
that with an alias ("strong reference").

b32cce1f82 Make generation of nslexer.c more robust.
Ensure that lex errors fail the build instead of being silently ignored
due to the piped call.  Also postpone the update of the nslexer.c file
until we are sure we have generated it properly.

These changes fix some very obscure build failures I encountered while
building FreeBSD within a chroot that did not have devfs mounted. The
specific errors looked like:

.../libc.so.7: undefined reference to `_nsyyerror'
.../libc.so.7: undefined reference to `_nsyyin'
.../libc.so.7: undefined reference to `_nsyylex'
.../libc.so.7: undefined reference to `_nsyylineno'
.../libc.so.7: undefined reference to `_nsyytext'

and were caused due to a mangled nslexer.c being linked into libc.

9f72c0322c Fix some edge cases with rewinddir():
- In the unionfs case, opendir() and fdopendir() read the directory's full
  contents and cache it.  This cache is not refreshed when rewinddir() is
  called, so rewinddir() will not notice updates to a directory.  Fix this
  by splitting the code to fetch a directory's contents out of
  __opendir_common() into a new _filldir() function and call this from
  rewinddir() when operating on a unionfs directory.
- If rewinddir() is called on a directory opened with fdopendir() before
  any directory entries are fetched, rewinddir() will not adjust the seek
  location of the backing file descriptor.  If the file descriptor passed
  to fdopendir() had a non-zero offset, the rewinddir() will not rewind to
  the beginning.  Fix this by always seeking back to 0 in rewinddir().
  This means the dd_rewind hack can also be removed.

While here, add missing locking to rewinddir().
