This library is dynamically loaded and used by bionic, to replace selected
standard socket syscalls with versions that talk to netd.
Implement connect() by requesting that the socket be marked with the netId of
the default network and then calling through to the actual syscall.
There are two escape hatches:
+ If the fwmark server is unavailable, it isn't an error; we proceed with the
syscall. This might help at boot time (when the server isn't ready yet) and if
we get rid of the fwmarkd socket entirely in future platform versions.
+ If the ANDROID_NO_USE_FWMARK_CLIENT environment variable is set, we don't
attempt to use the fwmark server (even if it's available). This allows apps to
sidestep unforseen issues in production at runtime.

The second macro parameter is named 'next' like listnode structure
'next' field. Since the precompiler will expand all 'next' occurrences
in the macro definition with what is passed by the caller, it is not
possible to call this macro with something else than 'next' as second
parameter.
This patch replaces the 'next' parameter with 'n' allowing use of a
next node not named 'next'.

printf*/scanf* libraries instead of Microsoft's ones which aren't always
C99 compatible. Declare "archetype" of attribute format to gnu_printf

One result is that "%z" (a gnu-extension) is accepted w/o warning by

This new version doesn't require any specialized thread
implementation, it uses the Current implementation to do its job.
In addition, it runs much faster when multiple threads are trying
to unwind at the same time since the global signal lock is held for
only a small amount of time. Even running through the threads one at
a time should be faster since it no longer requires two passes through
the unwound stacks.
The new code now allows multiple simultaneous unwinds of the
same thread.
Finally, add the ability to unwind from a ucontext_t passed in. This
functionality doesn't work for remote unwinds yet.

With AArch64 the enumerations with values in the range
0x80000000 to 0x80000007 are being assigned to ssize_t
typed variables which are 64-bit rather than 32-bit, and
are being used in conditions where they are being checked
for being negative. This is not the case when ssize_t is
64-bit, so redefine this to INT32_MIN value.

that the reserved field, which corresponds to the GGLsizei version
field in the GGLSurface structure (where GGLsizei is define as being
ssize_t in the system/core/include/pixelflinger/pixelflinger.h header
file) is uint32_t. That is appropriate to the 32-bit system but is
not appropriate to the 64-bit system, where ssize_t is 64-bits rather
than 32-bits.
The 32-bit system has also been tested and has no regression
because of this change.

Extract zip file processing logic from libdvm into a
standalone library.
This library is a stricter than the libdvm library in
several ways:
- Duplicate zip entry names are now disallowed. Files with
such entries will fail to parse.
- We now verify CD file size information with the individual
file header information. (This was pointed out as a deficiency
of this implementation in past discussions.)
- We also add support for crc checking, which means we might
need to parse the optional data descriptor footer (if one
exists).
We also provide an API for iterating over the entries of
a zip file. This library is optimized for two use cases :
- Lookup for a single entry in the file, with the intention
of processing or extracting the data associated with that
entry
- Iterating over all entries in a file *and* processing
/ extracting their data.
