Now you can filter the count statement with a selection
and selection args
UnitTests for this new methods are added to the cts project

1. move binding of args to one place - to SQLiteProgram
2. reduce locking time in SQLiteDatabase
3. reduce locking during time of binding of args
4. rmeove test for the deprecated ArrayListCursor
5. a couple of nits here and there

this should help developers figure out what various sqlite errors mean
and possibly programmatically handle them.

1. SQLIteStatement.executeUpdateDelete() replaces execute() - and returns the
number of rows changed.
2. let SQLiteDatabase.execSQL() call the above new API - which
means all CRUD statements by execSQL() are stored in prepared statement cache.
3. remove the following from SQLiteDatabase
lastrowId
lastchangecount()
native_execSQL()

seems this stuff is not used at all. a couple of CTS tests fail due to this code
not being corrected after recent changes to disable updates through cursor.

SQLiteCursor has two members: mQuery, mDatabase
but mQuery already has mDatabase.
there is no need for SQLiteCursor.mDatabase.
and everytime SQLiteQuery.mDatabase is to be used, try to use a pooled database
connection handle, if possible.

music2 app has the weird situation where it embeds the jumper C++ code
and that code uses its own version of sqlite.
so, java side may want to disable WAL to make c++ code work well with java
usage of sqlite.
since WAL is made default option for all apps, this CL makes it possible for
music2 app to disable WAL.

Now, when Thread A has a strict mode policy in effect and does a
Binder call to Thread B (most likely in another process), the strict
mode policy is passed along, but with the GATHER penalty bit set which
overrides other policies and instead gathers all offending stack
traces to a threadlocal which are then written back in the Parcel's
reply header.

Do compiling of sql, binding of args and execution of the SQL
statement within one single database lock period.
This reduces the number of times the database lock
needs to be acquired during the course of compilation, binding
and execution of a SQLiteStatement.

Some (including the Contacts app) do the following:
1. Open database
2. As part of database_connection.onCreate(),
Create some SQLiteStatement objects to cache them in the process
3. attach databases
WAL doesn't work with attached databases. so, apps doing the above
should enable WAL only if there are no attached databases.
But we would like to enable WAL automatically for all apps after step #1 above
and disable WAL if the app subsequently does 'attach database' SQL.
this works only if there are no SQLiteStatement objects created in step # 2,
because SQLiteStatements cwmaintain a hard-reference to the database connection
for life and also to the prepared SQL statement id.
It is quite difficult to disable WAL in step # 3
if it is enabled in step # 1
and then a connection pool gets used by step # 2
would make WAL disabling easier if SQLiteStatement refers to prepared SQL
statement id only when it is needed (during binding and execute calls)
and thus NOT tied to a spacific database conenction.
also, from the standpoint of not blocking readers, it helps NOT to have
SQLiteStatement be married to a database connection and prepared SQL statement
id for life.

this method causes sql statement in a SQLiteProgram object to be never
re-compiled. thats not desirable, is it?
there should be no need for this method.

- Move PackageInfo out of ActivityThread, renaming to LoadedApk.
- Rename some of the other PacakgeInfo inner classes to better
represent what they are.
- Rename HistoryRecord to ActivityRecord.
- Introduce AppGlobals, to eventually let ActivityThread become
package scoped.

an app can execute 'attach database..' statement anytime after WAL is
enabled. since WAL doesn't work with atatched databases,
disable WAL whenever the caller executes 'attach database'
sql statement.

due to a bug in DefaultDatabaseErrorHandler, if the corruption is
so bad that the list of attached databases can't even be retrieved,
then database is not closed in DefaultDatabaseErrorHandler,
this causes the corrupted file to remain on disk.
this causes corruption detection to occur forever until the stack
overflows.

two bugs were introduced by the above CL
1. to test if the column value is NULL, getType_native() should check if
the columnindiex is valid. (it seems sometimes callers could ask if a
given non-existent column is null - and the answer should be true.)
2. if a column is null and isBlob_native, isString_native methods should
return true - not false.
