    docs: update changelogs, push 3.11.8 release date out slightly

commit 7a41510fd68673f9327bfda71084f358618a595f

    selinux: make nsfs_t context conditional
    
    On some distos, nsfs_t isn't defined, and will cause the policy
    package to error when building or trying to install.  Make conditional.

    pmdadocker: Update help text

commit 216ee05026bc6cf41c07a606b3fae02c014a16a9
Author: Dave Brolley <[email protected]>
Date:   Tue Feb 14 13:51:35 2017 -0500

    Fix memory management regressions in __pmFetchInterp().
    
    - Don't use the return code of pmGetInDomArchive(3) to pre-allocate
      the hash table of instances, unless it is greater than zero.
    
    - Reduce the chance of a memory leak of the return buffer on error
      by waiting to allocate it until it is needed.
    
    These changes fix regressions in qa test cases 459 and 1079.

    RHBZ 1403095, RHBZ 1411720: Archive interp mode performance:
    
    Trim the unbound list as instances are resolved.

commit 307835bce5e5d598f8fa3d5812b6d2c4e2eeef93
Author: Dave Brolley <[email protected]>
Date:   Tue Feb 7 15:33:46 2017 -0500

    RHBZ 1403095, RHBZ 1411720: Archive interp mode performance:
    
    Traverse the ac_want list instead of the entire known metric space
    when possible.
    
    Eliminate the "zeroth" pass by initializing when added to the ac_want
    list.

Date:   Tue Feb 7 12:46:50 2017 -0500

    RHBZ 1403095, RHBZ 1411720: Archive interp mode performance:
    
    Don't initialize wanted and bound links in instance control blocks.

commit f824b83a172f5a7283e178a04cb01d888aa7001c
Author: Dave Brolley <[email protected]>
Date:   Tue Feb 7 11:37:46 2017 -0500

    RHBZ 1411720: Archive interp mode performance.
    
    Sort the ac_unbound list by time so that traversals can be
    abandoned early.

Author: Mark Goodwin <[email protected]>

    RHBZ 1403095, RHBZ 1411720: PmLogGetInDomArchive(3) performance.
    
    Use a hash table to detect duplicates for large instance domains.

commit d1fdea8d7d7721d78ed4367e1b5d4430132277a1
Author: Dave Brolley <[email protected]>
Date:   Mon Feb 6 12:19:25 2017 -0500

    RHBZ 1403095, RHBZ 1411720: Archive interp mode performance.
    
    Pre-allocate the hash t able of instances. This removes the overhead
    of growing it repeately when it is large.

commit 5926c9b0bd3b5af746bab0ecb469bc8d3f4f1b07
Author: Dave Brolley <[email protected]>
Date:   Wed Feb 1 16:04:45 2017 -0500

    RHBZ 1403095, RHBZ 1411720: Archive interp mode performance:
    
    Replace the linked list of instances for each pmid with a hash table.
    
    This results in an additional improvement of 50% for the test case
    for RHBZ 1403095 on top of earlier improvements. Running time is now 25%
    of the original.
    
    This results in an additional improvement of 80% for the test case
    for RHBZ 1411720 on top of earlier improvements. Running time is now
    7% of the original.
    
    Also fixed an error in __pmFreeInterpData(). The hash table buffer for
    the pmids was being freed while it was still being used.

commit c614fb0c8593a8379d4217b76496a5c2a933c96f
Author: Dave Brolley <[email protected]>
Date:   Tue Jan 31 15:50:16 2017 -0500

    RHBZ 1403095, RHBZ 1411720: Archive interp mode performance:
    
    update_bounds(): traverse the fetched instances in the outer loop and
    the nown instances in the inner loop. Reduces the time taken for both
    test cases by 50%.
