Re #12882.

It will become a library loaded through LD_PRELOAD so we keep the search
for it but move tcmalloc_minimal to be found first if it exists.
Refs #10271

Refs #9059

This now returns a human-readable string detailing the structure
of the workspace.
Refs #7708

If it is not closed then every call to verify the free memory leaves
open another process handle and very slowly leaks resources.

which overflowed the unsigned int giving billions of GB available

which overflowed the unsigned int giving billions of GB available

Also refs #4808, fix StartLiveDataTest

Added on the buffer onto the available memory.
Added a final debug message the prints the free and total memory.
Removed the 'scaling' factor on the cache that was being added
to the total free memory.

Work around windows not freeing up memory straight away causing the ManagedWorkspace performance test to fail. The ifdef will be removed when I check the linux and mac code. Refs #4023

Fixes #2588: Call to release memory only if above a certain threshold of memory used. Should save a couple of seconds vs calling it each time.

Refs #2568. Fixed the reserved memory calculation on Windows which was return 0. This meant that a workspace went managed even though the reserved memory could have saved it. Also re-enabled the low-fragmentation heap and mmap schemes which weren't being enabled in the right place. I've actually moved them to when the FrameworkManager starts up so that it happens as early as possible.
