DERBY-6884: SYSCS_IMPORT_TABLE_LOBS_FROM_EXTFILE can't import lob data
This change modifies the ImportLobFile.getString() and
ImportReadData.initExternalLobFile() methods so that they use a Java "long"
variable for the offset into the external lob file; prior to this change
they were using a Java "int" variable and hence would malfunction when the
lob offsets exceeded Integer.MAX_VALUE ( 2,147,483,647 ).
The regression test which demonstrates these problems is a bit slow to run;
on my system, it takes approximately 15 minutes to execute, and requires
about 10 GB of available disk space during the test run. Therefore, the
test cases are placed in a new test program (Derby6884Test), which is not
listed in the "standard" system test suites, but rather is only added to the
"largedata" suite. The new test can also be run by itself, e.g.:
ant -Dderby.junit.testclass=org.apache.derbyTesting.functionTests.tests.largedata.Derby6884Test junit-clean junit-single
