f84bc8d6f6 Test flags before using "info"
Our debugger signal catcher expects to receive three args, but if
somebody cleared SA_SIGINFO we only get one, and bad things happen
when we try to use the second one.  Test to see if SA_SIGINFO is
still set before we try to use the argument.

4688279db5 Clean up the linker a bit, remove prelinking support.
Also make the errors more readable, since none of us seemed to know
what they actually meant. The new style is still as verbose as the
old, but that's probably necessary in the absence of chained exceptions
in C. Here's what you'd see if you try to boot after removing
libsurfaceflinger.so:

  32267 32267 E AndroidRuntime: java.lang.UnsatisfiedLinkError: Cannot load library: (linker.c:1629, pid 32259) soinfo_link_image: could not load library "libsystem_server.so" needed by "libandroid_servers.so"; caused by (linker.c:1629, pid 32259) soinfo_link_image: could not load library "libsurfaceflinger.so" needed by "libsystem_server.so"; caused by (linker.c:709, pid 32259) load_library: library "libsurfaceflinger.so" not found

This patch also fixes almost all of the compiler warnings.

ca9a0712b8 Re-throw signals
If we catch a fatal signal that won't automatically re-throw when
the thread resumes, re-throw it manually.  (Common examples are
SIGPIPE and the SIGFPE from integer division by zero.)

3df3e672f5 Log the thread id and name for fatal signals.
This adds the thread id and name to the "Fatal signal" logging,
making it easier to track down where in process it actually crashed.

1fc51769de Log debuggerd connection failures
Write a message to the log file if the signal handler is not able
to connect to debuggerd.  This is especially handy if the failure
was caused by running out of file descriptors, since there's some
chance that the lack of fds relates to the crash.

Sample:

 F libc    : Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1)
 F libc    : Unable to open connection to debuggerd: Too many open files

ec92af8fe5 Log signal info at time of receipt
When a fatal signal is received, we now write a message to the log
that looks like this:

  F/libc    ( 1540): Fatal signal 11 (SIGSEGV) at 0xdeadd00d (code=1)

This is useful for debugging fatal signals that turn out not to be
fatal.  This also changes the signal reset from SIG_IGN to SIG_DFL,
so that future non-fatal fatal signals are fatal.

The code that blocked SIGUSR1 to avoid being interrupted by the GC
has been removed.

Also, fix minor issues in format_buffer().
