2e003f4324 Remove unused #defines from "arith.h".
These were defined in upstream's per-arch files, so I carried them across,
but they aren't actually used anywhere.

17e6a98b48 Make libc signal handler output more like debuggerd.
This has been annoying me for a while, because it's often quite misleading.

Today, for example, I saw:

  Fatal signal 13 (SIGPIPE) at 0x6573 (code=0), thread 25971 (top)

where the apparent address is actually the pid of the signal source (in this
case the kernel on behalf of the thread itself).

This patch isn't as fancy as strace, but it at least means we never say
anything misleading. We could decode the si_code field like strace and
debuggerd, but I'm reluctant to do that without some way to share the code
between at least bionic and debuggerd.

Examples after:

  Fatal signal 13 (SIGPIPE), code 0 in tid 9157 (top)
  Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 9142 (crasher64)
  Fatal signal 6 (SIGABRT), code -6 in tid 9132 (crasher64)

(Note that the code still shows as 0 for SIGPIPE in the signal handler itself
but as -6 (SI_TKILL) in debuggerd; this is actually correct --- debuggerd is
showing the re-raised signal sent at the end of the signal handler that
initially showed the correct code 0.)

2f68866f37 Make uselocale(3) claim its pthread key in an ELF constructor.
pthread_once is nice for decoupling, but it makes resource availability less
predictable, which is a bad thing.

This fixes a test failure if uselocale(3) is called before
pthread.pthread_key_create_lots runs.

dropped several symbols. This puts everything back in its proper place
and switches us to upstream head at the same time.

183ad9df53 Allow sharing the RELRO section via a file.
Add flags and a file descriptor to android_dlopen_ext() to allow writing
the RELRO section of the loaded library to a file after relocation
processing, and to allow mapping identical pages from the file over the
top of relocated memory in another process. Explicitly comparing the
pages is required in case a page contains a reference to a symbol
defined in another library loaded at a random base address.

12bbb91645 Support loading libraries to a reserved address.
Add flags and parameters to android_dlopen_ext() to allow loading a
library at an already-reserved fixed address. If the library to be
loaded will not fit within the space reserved, then the linker will
either fail, or allocate its own address space as usual, according to
which flag has been specified. This behaviour only applies to the
specific library requested; any other libraries loaded as dependencies
will be loaded in the normal fashion.

There is a new gtest included to cover the functionality added.

Add a function "android_dlopen_ext()", defined in <android/dlext.h>.
This is an extended version of dlopen() which takes a struct for passing
additional parameters for Android-specific functionality. This will be
used to support RELRO section sharing between separate processes.

Also add some missing aliases. We now have all of:

  isnan, __isnan, isnanf, __isnanf, isnanl, __isnanl,
  isinf, __isinf, isinff, __isinff, isinfl, __isinfl,
  __fpclassify, __fpclassifyd, __fpclassifyf, __fpclassifyl.
