String#substring has become significantly slower as of JDK 1.7.0_06 [1],
such that there are performance degradations by a factor of 100-1000 in
ResourceDatabasePopulator, especially for large SQL files.
This commit works around this problem by minimizing the substring scope
to the least amount possible to prevent unnecessary internal copying of
strings (which seems to cause the issue).

Issue: SPR-9781
The reference manual currently documents the wrong file name for the
default data SQL script used by EmbeddedDatabaseBuilder. In addition,
the testing chapter of the reference manual does not link to the testing
section of the JDBC chapter.
- Updated the "Testing data access logic with an embedded database"
section of the reference manual appropriately.
- Added a new paragraph to the "JDBC Testing Support" section of the
testing chapter which cross references the "Testing data access logic
with an embedded database" section.

Previously, DatabasePopulatorUtils#execute looked up a Connection from
the given DataSource directly which resulted in the executed statements
not being executed against a transactional connection (if any) which in
turn resulted in the statements executed by the populator potentially
not being rolled back.
Now DataSourceUtils#getConnection is used to transparently take part in
any active transaction and #releaseConnection is used to ensure the
connection is closed if appropriate.

This patch fixes several compiler warnings that do not point to code
problems. Two kinds of warnings are fixed. First in a lot of cases
@SuppressWarnings("unchecked") is used although there are no unchecked
casts happening. This seems to be a leftover from when the code base
was on Java 1.4, now that the code base was moved to Java 1.5 these are
no longer necessary. Secondly there some places where the raw types of
List and Class are used where there wildcard types (List<?> and
Class<?>) would work just as well without causing any raw type warnings.
These changes are beneficial particularly when working in Eclipse or
other IDEs because it reduces 'noise', helping to isolate actual
potential problems in the code.
The following changes have been made:
- remove @SuppressWarnings where no longer needed
- use wildcard types instead of raw types where possible
SPR-7680 added QueryTimeoutException to Spring's DataAccessException
hierarchy, but did not integrate it into the
SQLExceptionSubclassTranslator; it was added mainly to accomodate users
defining their own custom exception translators.
However, it does make sense to translate any SQLTimeoutException to this
new QueryTimeoutException type, and this commit makes that change. It
does represent a slight backward-incompatibility, given that
QueryTimeoutException extends TransientDataAccessException, whereas
SQLExceptionSubclassTranslator previously returned the more specific
TransientDataAccessResourceException for any SQLTimeoutException.
It is expected that this incompatibily will be very low-impact, i.e. not
affecting many (if any) users. In any case, a major release (Spring 3.2)
is the right time to introduce such a change, and the migration path is
straightforward: any users depending on catching
TransientDataAccessResourceException in the case of query timeouts
should update those catch blocks to expect QueryTimeoutException
instead. Care should also be taken to ensure correctness of existing
catch blocks expecting TransientDataAccessException, as these blocks
will now catch QueryTimeoutException as well.

Before this change there were numerous javadoc warnings being reported
while building Spring framework API.
This commit resolves most of the javadoc warnings, reducing the total
number from 265 to 103.

This renaming more intuitively expresses the relationship between
subprojects and the JAR artifacts they produce.
Tracking history across these renames is possible, but it requires
use of the --follow flag to `git log`, for example
$ git log spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history up until the renaming event, where
$ git log --follow spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history for all changes to the file, before and after the
renaming.
