Compilation issues fixed by rolling back offending revision.
Version bumped to 1.7.7-SNAPSHOT; changelog updated.
SVNKIT-317: Added a regression test (it checks if SQLJet version used is correct).
Failed with SQLJet 1.1.4 but succeeds with 1.1.5 (current version).
Fixed compilation for Java 5.
SVNEvent objects with the SKIP action generated by upgrade operation should have not null expected action value (e.g. SVNEventAction.UPGRADED_PATH).
SVNChecksumInputStream internal buffer made non-static; concurrent operations might damage that buffer contents.
SKIP even action should either be accompanied by expected action which is not SKIP or by null as an expected action.
SVNKIT-324: NPE while WC 1.6 to repository copy: added a regression test.

The problem has been already fixed at r9475.
SVNKIT-322: For files which pristine content was already present in .svn/pristine update always
reused timestamp of the pristine file (instead of setting it to the current time), now fixed.

This behaviour confused build tools that rely on monotonical increase of file timestamps.
SVNKIT-325: No file.edited should be created if ISVNConflictHandler provides SVNConflictResult with mergedFile even if SVNConflictChoice is POSTPONE.
Fixed compilation for Java 5.
Repository file size was not reported by recursive remote info operation, fixed.
SVNKIT-326: Added a test that moves a directory with a moved file, works fine.
wc.db ACTUAL_NODE table created by an older versions of SVNKit or Subversion might contain empty strings in place of null. This might result in failure on conflict resolution, now should be fixed.
SSL protocols supported by SSL socket made configurable via a static method.
SVNKIT-331: keepLocks in SVNKit/SVN should mean the same as noUnlock in JavaHL interface.
HTTP realm that is used to cache credentials should include user name specified in the URL, if any.
SVNKIT-334: SVNCommitPacket#setCommitItemSkipped is not supported with SVNKit 1.7. Added a failing test.

The problem excists because new API SvnOperationFactory-based doesn't support items skipping.
So the fact of commit item skipping is lost while conversion between old and new APIs.
SVNKIT-332: Added a reproducing test. The problem occurs on Windows if a file in repository contains a backslash.
SVNKIT-333: Moving between working copies caused losing of all actual (not base) properties for WC 1.7, now fixed.
