e83c56dfbb Execute .preinit_array before any shared object initialization functions.
This change makes linker handling of .preinit_array compliant with the
System V ABI:

"These [pre-initialization] functions are executed after the dynamic linker has
built the process image and performed relocations but before any shared object
initialization functions."

1698d9ebfc Fixed support for RTLD_NEXT in dlsym()
The previous implementation of this flag was broken--it behaved identically
to RTLD_DEFAULT.  This adds a proper implementation, which examines the address
of the calling function, and uses it to determine which library to use to begin
the symbol search process.

e2a8b1fd19 Added support for dladdr()
dladdr() is a GNU extension function, which allows the caller to retrieve
symbol information for a specified memory address.  It is useful for things
like generating backtrace information at runtime.

5c734644ee Fix debug output in the dynamic linker.
This provides a mini-printf implementation that reduces the
size of the dynamic linker by 25 KB, by preventing the drag of
formatting-related routines from the C library.

Also allow traces to be sent to the log, instead of stdout.

NOTE: You now need to modify Android.mk to enable/disable debug
      output.

2e85579c34 linker: Make the errors reported by dlopen/dlsym be more useful.
Changed it so that when the linker generates error messages, they are
scribbled away into a buffer that dlfcn and friends can read from.

Since the error messages are generetad with snprintf, and snprintf
MAY call malloc during some code paths, we now link against a version
of libc that does not contain malloc/free/realloc/calloc. We then define
malloc and friends in the dynamic loader, and make them abort() if they
are ever called.
