This patch mainly to update DOM Cahce's usage to the QuotaManager when a file
is deleted. This patch implement two helper function to delete the nsIFile
recursively or directly and update usage to QuotaManager.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

Before this patch, we would only set these pragmas as part of CreateSchema
which runs in SetupAction. This meant that the connection used to perform
other DBActions would not have had these pragmas applied. As a result,
sqlite would not honor foreign keys on such connections, so the cascade
delete rules responsible for deleting rows from request_headers and
response_headers would not get executed when DBSchema::CachePut deleted the
old entry before adding a new one.
The test in the patch demonstrates how this could result in an observable
breakage. Before this patch, the response headers stored in the cache for
the overwritten entry would reflect both `Mirrored: `foo' and `Mirrored: bar'
headers, which means that attempting to get this header on the cached
response would return the first entry, `foo'.
