libevent-2.1.10

[Douglas R. Reno]

New point version

[Douglas R. Reno]

Changes in version 2.1.10-stable (26 May 2019)

 This release contains mostly fixes (some evbuffer oddity, AF_UNIX handling in
 http server, some UB fixes and others) but also some new functionality
 (without ABI breakage as usual) and now dist archive can be used for building
 on windows (getopt had been added into it).

 Above you will find changelog for this particular release (but with some
 trivial fixes pruned out from it - to make it a little bit more informative).

Changes in version 2.1.9-beta (10 February 2019)

 This changelog will differs from other releases in the next few clauses:
 - contains only highlighted changes (so now it will not contains a lot of
   patches that fixes some stuff in regression tests, typos, leaks fixes in
   samples and so forth)
 - no authors (since merge commits breaks them anyway, but AUTHORS sections in
   README will be kept up to date)
 - group name trimmed from commit subjects trimmed
 - it's been 2 years since the previoius release, so it is pretty huge

 And I think that this is more useful, so from now on it will always has the
 same look (until there will too many objections of course).
