AER-3017: has_sindex information should be collected after taking record lock
Update modules/mod-lua (64-bit Lua cache counters).
Fix typo.
[QUERY] Fix for query_aggregation, when client closes connection before
processing all the result.
Don't Enabled LDT in Developer Config. File.
Merge branch 'agg_memleak_fix'
AER-3065 - security refinement - internal LDT UDFs no longer require UDF privileges, they are recognized as read or write operations.
Merge branch 'master' into has_sindex_fix
comment cleanup
AER-3069 - fixed UDF timer to handle nanosecond end-times properly.
AER-3070 -- Aerospike Daemon Init. Script Prints Error Message Due to Huge SHM Kernel Settings.
Problem:  BASH is limited to 63-bit integers, while the Linux kernel defaults are now 64-bit integer values.
* Add tests that safely ensure the requisite minimum values for "kernel.shmall" and "kernel.shmmax" by first testing number of digits prior to testing vs. the required minimums.
* Also made the RHL / Debian init. scripts match more closely by removing needless ordering differences.
Thanks to Chetan V. for help with this solution.
AER-3057 aggregation digest array leak fixed
Merge pull request #32 from citrusleaf/agg_leak_fix

AER-3057 aggregation digest array leak fixed
AER-3071 - discover minimum size needed for device IO operations using O_DIRECT.
(This used to always be 512 bytes but is now 4K on some newer SSDs.)
AER-3067 - defrag enhancement - added 'defrag-queue-min' configuration parameter to specify delay in processing defrag-eligible wblocks.
This should benefit particular usage models in which wblocks continue depleting quickly and significantly after crossing their defrag-eligibility threshold.
Enhancement to asinfo - added ldt-enabled value to the namespace config info output.
Also, removed an unused buffer.
Refine Comment.
