88f06cd84a Use private futexes for pthread_mutex_t.
This does not change the implementation of conditional variables
since we're waiting for other system components to properly use
pthread_condattr_init/setpshared before that.

Also remove an obsolete x86 source file.

ee7b077abf Add pthread_condattr_init/destroy/setpshared/getpshared
Note that this does not change the implementation of conditional variables
which still use shared futexes, independent on the flags being selected.

This will be fixed in a later patch, once our system is modified to use
pthread_condattr_setpshared(attr, PTHREAD_PROCESS_SHARED) properly.

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.

ba9c6f0989 bionic: pthread: use private futexes by default for mutexes and condvars
Private futexes are a recent kernel addition: faster futexes that cannot be
shared between processes. This patch uses them by default, unless the PROCESS_SHARED
attribute flag is used when creating a mutex and/or conditional variable.

Also introduces pthread_condattr_init/destroy/setpshared/getpshared.

8132626b71 Fix strtod security bug.
To avoid introducing NULL checks everytime a Bigint computation
is performed, introduce a special value (BIGINT_INVALID) and only
check for it when absolutely needed (which means when the code
needs to access the Bigint's internal structure fields).

d378c68d74 Fix spurious DNS lookups in the C library.
The problem was that the 'defdname' field of res_state structure
was not properly initialized in __res_vinit(). This field is used
to store the default domain name, which is normally build from
calling gethostname() (see line 549 of res_init.c).

Unfortunately, in the typical Android case, gethostname() returns
an error (the hostname is configured) and a random stack string is
used later to build the DNS search list (see lines 556+ in res_init.c)

For the sake of illustration, let's say the search list is set to
a random value like 'xWLK'.

The end result is that when trying to result an unknown domain name
(e.g. 'www.ptn'), the query fails then the resolver tries to make a
new query with the DNS search list path(s) appended (e.g. 'www.ptn.xWLK').

The patch simply initializes 'defdname' to an empty string to avoid
this when the net.dns.search system property is not set.

Also contains whitespace/formatting fixes

9ab75d4cc8 Implement support for RFC 3484 (address selection/sorting) in bionic. (The
Java changes required not to mess up the ordering from bionic will arrive in a
later commit.) In particular, this will give us more correct behavior when on a
6to4 network, in that IPv4 will usually be preferred over 6to4.

Most of RFC 3484 is implemented -- what's not is rule 3 (avoid deprecated
addresses), 4 (prefer home addresses) and 7 (prefer native transport) as they
require low-level access to the kernel routing table via netlink. (glibc also
started out this way, and these rules are primarily useful in pretty obscure
circumstances, so we should be fine for the time being.)

Also, rule 9 (use longest matching prefix) has been modified so it does not try
to sort IPv4 addresses; given current IPv4 addressing practice these rules are
pretty much meaningless. Finally, I've added support for Teredo as a separate
label, with slightly lower preference than 6to4. (Vista puts the preference
below IPv4 by default. glibc puts the preference together with non-tunneled
IPv6.)

Note that this patch removes support for the "sortlist" directive in
resolv.conf; I've never seen it in actual use, it's irrelevant for Android
(since we don't use resolv.conf anyway), and it's not clear how it would be
implemented alongside RFC 3484.

e31c1d0b48 Fix pread()/pwrite() stubs
On ARM EABI, 64-bit function parameters must be aligned
to an even/odd register pair.  The weird way these stubs
were written (using separate lo/hi parameters) prevented
this alignment from being enforced by the compiler.

This provides a mini-printf implementation that reduces the

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.
