added HDF5 version check
1. Attempted to reduce the number of conversion errors
   when -Wconversion is set. Fixed libdispatch, but
   rest of netcdf remains to be done.
The replacement of 'int' with 'size_t' caused a number of errors across multiple platforms in our CI system.  The culprit is not obvious, so I am reverting the commit until we can take a closer look at the underlying issue.

Revert "1. Attempted to reduce the number of conversion errors"

This reverts commit 1b941d342d5614aec5f55f819c0ee590e8bd3d6e.
1. Previous ci of conversion fixes in libdispatch
   was incomplete; complete the fix.
2. There is an inconsistency in the netcdfh interface
   about whether rank (# dimensions) is an int or
   size_t. I inadvertently assumed the latter and that
   breaks some API calls; so revert back.
conflict resolution
Removed stray 'conflict resolution' information.
turn on tst_auth
conflict resolution
update the url in t_auth
Add support to detect authorization errors to DAP
Merge branch 'master' of http://github.com/Unidata/netcdf-c
Added checks for CURLOPT_KEYPASSWD and CURLINFO_RESPONSE_CODE in CMakeLists.txt for DAP-enabled builds.
Added define for HAVE_CURLINFO_RESPONSE_CODE in config.h template for cmake-based builds.
Merge branch 'hdf5-version-check' of https://github.com/nschloe/netcdf-c into nschloe-hdf5-version-check
Added a stanza for cases where the hdf5 library version cannot be determined.
Updated download link in README.md
Moved check for libdl before the check for libhdf5.  This way, when working with static libraries, libdl will be used when compiling the libhdf5 test program.
coads_climatology test (tst_varm3) now works, t_auth still does not
Added test_varm3 back in to the list of active tests, to keep it in step with autotools.

Corrected configure.ac; CURLOPT_RESPONSE_CODE should have been CURLINFO_RESPONSE_CODE.
Added tst_bom.sh to EXTRA_DIST, fixing a failure in 'make dist'.
