Reorder the find permission checks. This avoids generating misleading
SELinux denials when a service doesn't exist, or when a service is
prohibited to isolated apps.
The original reason for structuring the code this way is explained
in https://android-review.googlesource.com/#/c/100530/4/cmds/servicemanager/service_manager.c@172
The concern at the time was to avoid leaking a situation where
a caller could probe for the existance of a service. This turns out
to be unnecessary. The same return value is used for both a
permission denied and a service not found. The only side effect
is the generation of an SELinux audit log, which likely won't be
accessible to the calling application.

Call logcat -L to pull any LAST Android logs. If the kernel is not
configured for PSTORE and PSTORE_PMSG, the hopes are the empty
content will pressure vendors to slice up and configure support.

It turns out dump_file is used on a number of /proc and system files.
In one case, the read of a file stalled and caused a bugreport to
hang forever. It's still possible if there is a kernel bug that this
could stall forever, but less likely.
Also, change the return type of nanotime to uint64_t.
Testing:
- Created a named fifo and verified that dump_file fails with a timeout.
- Created a large /data/anr/traces.txt to verify that large files still
dump properly and that the additional NONBLOCK parameter doesn't cause
a problem.
- Created a dummy /data/tombstones/tombstone_00 to verify that the
dump of these files still works.
- Compared a dump using the old dumpstate to the new dumpstate to verify
nothing obviously different.

Some time before kitkat, a workaround was put in place to keep tuna
working with obsolete PowerVR GPU drivers. The tuna product was dropped
in AOSP for kitkat, but the workaround remained.
There are still a number of devices shipping with OMAP4 processors, and
this workaround continues to be applied on those products even when it
is not required. The effect is that virtual display CTS will fail on
those devices.
This option doesn't work with the current selinux protections and
doesn't serve much of a purpose. You can get the same results running
this:
dumpstate | gzip > /data/local/tmp/dump.txt.gz

Implemented these changes:
- Make this code C++.
- Avoid hangs by adding a timeout.
- Add the necessary TEMP_FAILURE_RETRY calls.
- Restructure the code a bit.

Avoid ambiguity by using register numbers. Register names are
interpreted depending on the ABI. Fixes the issue with mips64 gcc,
where registers t0-t4 are translated into $8-$11 (o32 ABI) instead
of $12-$15 (o64 ABI).
Also, use t9 ($25) for storing function address
(in getProcAddress.cpp).

Combines 4 patches by Dragoslav and Douglas:
Use t9 to hold the address of the called function.
Add support for gl binding.
Fix inline assembly code to be R6 compatible.
Fix some more inline assembly code to be R6 compatible.

Use the native stack dumping functions that allows time outs. If
debuggerd locks up, before a bugreport would hang forever. Now
it will timeout properly and still get all of the other information.

When compiling 32 bit binaries against a 64 bit binder interface,
implicit promotions of intptr_t types to uint64_t for fields in the
binder ioctl structures can result in invalid pointers because of sign
extension.
