2.5.10 patch 3

• All output to stdout/stderr now goes through an internal logging function.
  The log messages can optionally be redirected to a user supplied function
  (by default they are written to stderr).
• Some headers that are internal to the library are no longer installed.
• Restored possibility of compressing the output files (Denis Rosset).
• Remove unused support for dmalloc.
• Convert demo_qs into test_qs TAP test suite.

2.5.10 patch 2

• (The patch _p version notation used in 2.5.10_p1 is not widely supported so
  this release simply uses the dot notation.)
• Removes Python module (moved to separate repository at
  https://github.com/jonls/python-qsoptex).
• Move library source files into qsopt_ex so the header files can be accessed
  in the same way as when installed (<qsopt_ex/XX.h>).
• Explicitly include the typename of template types when using a macro,
  variable or function that is template generated. This removes the
  build dependencies on Exuberant Ctags and GNU sed, as well as speeding up
  the template generation significantly.
• Remove util.c/util.h from template generation since the majority of symbols
  are not template type specific.

2.5.10 patch 1

• Based on original version v2.5.10 published by Daniel Espinoza et al.
• Changed to autotools-based build system.
• Removed external dependency on EGlib.
• Build library using libtool for portability.
• Add Cython-based Python module to interface with libqsopt_ex.
• Fix sprintf calls with missing format string.
• Add missing header declarations, includes.
• Clean up headers to make external use easier.
• Remove some unused functions/macros that caused compiler warnings/errors.
• Workaround: Writing solution to gz-file was broken; temporarily disabled gzip output.
• Add README file with build instructions and code examples.
• Add Travis CI build script.
