DropBox and EventLogger provide hooks for use by framework to intercept
messages sent by libcore. However, neither of these mechanisms are
actually used by libcore so there is no point in framework code using
it.

This reverts commit 766b425c27.
Appears to be the cause of a 14ms regression in wifi startup time in system server that could be offset here (and potentially other places) by keeping the preload in zygote. A local trial of five showed this revert to take it 111.2ms -> 108ms. The variance is likely too high for this to be significant, however, logically, in the short term, these libraries are being used, and so preloading makes sense. I'll leave further changes to this list to the owners of this list.
Test: boot walleye 5 times w/ and w/o this test, and find small gain in reverting this.
Reason for revert: b/115771598

Update preloaded-classes to track libcore class renames.
The class renames may have caused a regression in some
performance metrics, though overall boot time was unaffected.
This is probably because the first user is now paying the cost
of the class initialization and that happens to be in the affected
metrics. There's no reason not to update the preloaded-classes.
Metrics affected:
SystemServerTiming_StartUsageService_avg
SystemServerTiming_StartJobScheduler_avg
SystemServerTiming_StartJobScheduler_avg

All violations of StrictMode now inherit from one central Violation
class. This unlocks adding penaltyCallback(Violation).
Parsing strings is no longer required to infer what type of violation
something is.
Violation classes have no need to be loaded in Zygote as only developers
opt-in to this feature and will see violations.

Change I686e3c20f5860e58825e1b88f220f9b8c335849c removed the
org.apache.http.legacy library from the bootclasspath which means that
the classes are no longer available to be preloaded by the zygote. This
change removes the classes that cannot be preloaded from the list of

Updated the system server profile, moved to using a profile for the
boot image.
Use cases for obtaining profiles:
Automated CUJ tests
Automated app launches
Manual usage of dialer, navigation, playstore, and play music.
Storage savings:
Boot art+vdex+oat size: 78305556->61539326 (-17MB)
New system server profile has more methods (1.5MB -> 4MB oat) since it
has more coverage from use cases.
Ram savings (sample averages for CUJ test):
Average PSS of 3 runs (~100 samples total):
.Boot_vdex: 9359K -> 9902K
.oat_mmap: 21857K -> 13372K
.Heap: 29779K -> 29483K
.Boot_art: 15736K -> 18096K
.LinearAlloc: 9112K -> 8965K
Total PSS: 85846K -> 79819K (-6MB)
Average pages read from flash (512MB device) for CUJ tests (3 samples):
1508MB -> 1183MB
TODO: Investigate why .art goes up, maybe we are missing some classes
in the profiles.
