[TRAFODION-2626] Change path of sqconf, ms.env, sqcert, udr and related files

This changeset covers the remaining instances of hard-coded paths based

on TRAF_HOME for dynamic files that should be in specific paths such as

TRAF_CONF or TRAF_VAR.

All files referenced via TRAF_HOME should be read-only software, not written

during run-time.

[TRAFODION-2626] Make logs directory location configurable

Makes path to log directory independent of TRAF_HOME. The default location

is still $TRAF_HOME/logs. The DCS and REST log directories are now

sub-directories of the main TRAF_LOG directory.

[TRAFODION-2821] Trafodion core code base needs to be thread safe

Changes as per review comments in commit d940a4a183

[TRAFODION-2821] Trafodion core code base needs to be thread safe

TMLIB JNI interaction was not thread safe causing T2 driver application

to dump core at times.

Cleaned up TMLIB JNI interaction and added lock mechanism such that JNI

methods are initialized by one thread in a thread safe manner.

[TRAFODION-1988] Better java exception handling in the java/JNI layer in TM

The following problems are fixed:

The loaded classes reference are made global to avoid the class reference from gc-ed

Introduced push/pop frame concepts to avoid memory growth usually observed with

many JNI/java transitions

Logged the errors via log4cxx mechanism instead of stdout

Possibly fixes the tm core dumped in obscure way at times

[TRAFODION-2170] certain create table DDL will fail with core dump

[TRAFODION-2296] Consistent error reporting in abort, commit transaction. Changes to wait for all RS to respond when there is an exception in abort and commit transaction requests.

When there is an error returned from commit or rollback transaction, the details of the error can be obtained in the following log files

a) $MY_SQROOT/logs/tm_.log in the node that issued this request contains the error message as seen by the TM process in the JNI side. This event may not have transaction id.

b) $MY_SQROOT/logs/trafodion.dtm.log contains more info about this error with the transaction id. These events are logged from java side of TM.

c) In the region server logs of all the regions that participated in the transaction.

These exceptions are visible as error code on the client side. To get the details about the exception, the above logs need to be browsed.

Fixes to avoid tm core upon double delete of incoming messages to it

This closes #768
