Switch the rest of our internal headers to #pragma once.
We've been using #pragma once for new internal files, but let's be more bold.

Add support for disabling the greylist.
Useful for testing whether apps have actually stopped using greylisted
libraries even if they still have references to them in their apk to support
old Android releases but also haven't bumped their targetSdkVersion yet.
Since we already have two expensive __system_property_get calls and this
would add a third, optimize two (but leave the third since it's not
obviously amenable to optimization). None of this matters for user builds,
but I don't want userdebug/eng to have distractingly different performance.
(cherrypick of 7933bec2872aa1c3430149c7649726333c0ac9d8.)

Add a way to track all dlsym calls
Add dlsym option to debug.ld.all and debug.ld.app.<appname> which
enables logging of dlsym calls.
Bug: http://b/29458203
Test: flash, set debug.ld.all to dlsym and check
if there are messages in logcat

Pass argc/argv/envp to dso constructors
The glibc implementation of the loader passes argc/argv/envp
to all elf constructors. This change makes bionic linker
behave in the same way.

linker: Enable debug logging via properties
This patch lets developers tune logging of dlopen/dlerror with
setting system property.
Note that for security purposes this option is disabled on user build
for non-debuggable apps.
For starters there are 3 debug options:
dlerror - enables logging of all dlerrors
dlopen - traces dlopen calls
To enable system-wide logging (works only for userdebug/eng builds)
use debug.ld.all property.
To enable logging for particular app use debug.ld.app.<appname> property.
Example: Running "adb shell setprop debug.ld.all dlerror,dlopen" will log all
dlerror message as well as trace all calls to dlopen.
