718fbb1dc6 libc: stop exporting cerror
i386 stopped exporting .cerror in r240152, and likewise for amd64 in
r240178. It is not used by other libraries on any platform, so apply
the same change to the remaining architectures.

d4d16ecba2 libc: stop exporting curbrk and minbrk in the private namespace
They are not used anywhere else in the base system and are an internal
implementation detail that does not need to be exposed.

a65b4d5170 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").

a88ca47b66 Per kib, since __flt_rounds is being added to FreeBSD 10, it
belongs in FBSD_1.3.

261e450cc4 __flt_rounds is a public symbol (expands from the FLT_ROUNDS macro),
so include it in the public namespace on arm just as with
other architectures.

This corrects r236816.

9373f7b9c4 Replace a proliferation of buggy MD implementations of modf() with a
working MI one.  The MI one only needs to be overridden on machines
with non-IEEE754 arithmetic.  (The last supported one was the VAX.)
It can also be overridden if someone comes up with a faster one that
actually passes the regression tests -- but this is harder than it sounds.

f291262336 Some libc symbol map cleanups.
net: endhostdnsent is named _endhostdnsent and is
  private to netdb family of functions.

  posix1e: acl_size.c has been never compiled in,
  so there's no "acl_size".

  rpc: "getnetid" is a static function.

  stdtime: "gtime" is #ifdef'ed out in the source.

  some symbols are specific only to some architectures,
  e.g., ___tls_get_addr is only defined on i386.

  __htonl, __htons, __ntohl and __ntohs are no longer
  functions, they are now (internal) defines in
  <machine/endian.h>.

b52ec536bb Remove .mcount from gmon's Symbol map and add it to the appropriate

_mcount).
