This property provided a way to disable the greylist, for testing
whether an app targeting < 24 still works. Instead of turning off the
greylist, though, an app developer should simply target a newer API.
(If app developers really need this property for testing, they can
still use it on versions of Android between N and R, inclusive.)

- Show which executable is being linked, which linker config file is
being read, and which section in it is being used with, enabled on
$LD_DEBUG>=1.
- Show more info to follow the dlopen() process, enabled with "dlopen"
in the debug.ld.xxx property.
Test: Flash, boot, and look at logcat after "adb shell setprop debug.ld.all dlopen"

Avoids some unnecessary work during dlopen/dlclose/dlsym for most
cases.

Use <android-base/macros.h> instead where possible, and move the bionic
macros out of the way of the libbase ones. Yes, there are folks who manage
to end up with both included at once (thanks OpenGL!), and cleaning that
up doesn't seem nearly as practical as just making this change.

We've been using #pragma once for new internal files, but let's be more bold.

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.

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

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

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.
