[TRAFODION-3110] Refactor LOB access to use the new implementation of HdfsClient

Used a single CQD USE_LIBHDFS to switch to older implementation of

using libhdfs for both hdfs scan and LOB access. The CQD USE_LIBHDS_SCAN is


In addition fixed the following:

1. Fixed a memory leak of LOB Heap structures

2. Possible fix for memory corruption at times

3. Avoid unnecessary creation of LOB threads when not needed

[TRAFODION-2738] Rowset buffer size during insert/upsert should be limited

Rowset insert includes UnpackRows operator in its query tree. UnPackRows

operator was allocating a larger memory based on rowset size and row size

to flow the data to its parent operator.

Introduced a CQD EXE_MEMORY_FOR_UNPACK_ROWS_IN_MB to limit the amount

of memory allocated in this operator. The default value is 100MB.

In addition, streamlined the NAMemory infrastruture to return NULL or

dump core when more than 2 GB of memory is allocated in one chunk.

Ensured that CQD NUM_ESP_FRAGMENTS can take value upto 8. Removed the environment variable concept to set the number of esp fragments. Removed the CQDs ESP_NUM_FRAGMENTS_WITH_QUOTAS and ESP_MULTI_FRAGMENT_QUOTAS. Use the corresponding CQD ESP_NUM_FRAGMENTS and ESP_MUTLI_FRAGMENT instead (cherry picked from commit 72534e89633f3d4b8a61ab26d471aaa8b7f3e12a)

[TRAFODION-2314] MXOSRVR sometimes exits abnormally with NAMutex assert

Fixes as suggested by Selva and Sandhya.

We were hitting the code to make heap thread safe repeatedly while running

jdbc and phoenix tests.

PROCESS_LOB flag was being set incorrectly in some cases.

Unlocking a mutex owned by a different thread lead to the assertion.

This could also result in heap corruption.
