XA Interleaving Pull Requests

<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dave (and the rest of the list),<br
/><br/> I finally made the time today to sift through our XA implementation code, separating it out so it does not
interferewith the original PGXADataSource code, and coalescing the commits in a second branch of our github
repository.<br/><br /> I think this should address all the concerns I made note of back in January & February.<br
/><br/> I've issued two pull requests which make the following changes:<br /><br /><a
href="https://github.com/pgjdbc/pgjdbc/pull/64">https://github.com/pgjdbc/pgjdbc/pull/64</a><br/>  * Respect the
${srcdir}in the ant build.xml.<br /><br /><a
href="https://github.com/pgjdbc/pgjdbc/pull/65">https://github.com/pgjdbc/pgjdbc/pull/65</a><br/>  * Make minor changes
tothe class hierarchy for PGXADataSource<br />  ** Expose a pooled connections underlying Connection to sub-classes.<br
/> ** Makes the abstract classes actually Abstract, and pushes the responsibility of creating an XAConnection object
downto the concrete implementation (PGXADataSource).<br /> ** Introduces the PGFullXA* classes, which represent the
alternateimplementation we cooked up for fully supporting interleaving.<br /> ** LOTS of test cases! :-D<br /><br /> To
usethis implementation instead of the original PGXADataSource, just change your XA data source class to
PGFullXADataSource.<br/><br /> I look forward to the review of these pull requests!<br /><br /> Regards,<br /> -Bryan
