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").

system libraries, for example libm.

061103347c Per kib, since __flt_rounds is being added to FreeBSD 10, it
belongs in FBSD_1.3.

ed1589b9b7 __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.

6232589aeb 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.

2665faf497 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>.

f0cd539d5e Do not export 'end' symbol. It is not meant to be visible to outside
world and it wreak havoc if libc collides with other versioned
libraries.

0c58e013aa Remove .mcount from gmon's Symbol map and add it to the appropriate
arch.  It can be named differently depending on the arch (.mcount,
_mcount).
