Update cygwin.c for new mingw-64 win32 api headers

The cygwin project recently switched to a new implementation of the
windows api, now using header files from the mingw-64 project. These
new header files are incompatible with the way cygwin.c included the
old headers: cygwin.c can be compiled using the new or the older (mingw)
headers, but different files must be included in different order for each
to work. The new headers are in use only for the current release series
(based upon the v1.7.x dll version). The previous release series using
the v1.5 dll is kept available but unmaintained for use on older versions
of Windows. So, patch cygwin.c to use the new include ordering only if
the dll version is 1.7 or higher.

Merge branch 'jc/maint-fetch-tighten-refname-check'

For a fetch refspec (or the result of applying wildcard on one), we
always want the RHS to map to something inside "refs/" hierarchy.

This was split out from discarded jc/maint-push-refs-all topic.

* jc/maint-fetch-tighten-refname-check:
  get_fetch_map(): tighten checks on dest refs
Merge branch 'jh/symbolic-ref-d'

Add "symbolic-ref -d SYM" to delete a symbolic ref SYM.

It is already possible to remove a symbolic ref with "update-ref -d
--no-deref", but it may be a good addition for completeness.

* jh/symbolic-ref-d:
  git symbolic-ref --delete $symref
Merge branch 'jk/maint-diff-grep-textconv'

Fixes inconsistent use of textconv with "git log -G".

* jk/maint-diff-grep-textconv:
  diff_grep: use textconv buffers for add/deleted files
Merge branch 'ph/submodule-sync-recursive'

Adds "--recursive" option to submodule sync.

* ph/submodule-sync-recursive:
  Add tests for submodule sync --recursive
  Teach --recursive to submodule sync
Merge branch 'jc/same-encoding'

Various codepaths checked if two encoding names are the same using
ad-hoc code and some of them ended up asking iconv() to convert
between "utf8" and "UTF-8".  The former is not a valid way to spell
the encoding name, but often people use it by mistake, and we
equated them in some but not all codepaths. Introduce a new helper
function to make these codepaths consistent.

* jc/same-encoding:
  reencode_string(): introduce and use same_encoding()

Conflicts:
	builtin/mailinfo.c
Merge branch 'cr/cvsimport-local-zone'

Allows "cvsimport" to read per-author timezone from the author info
file.

* cr/cvsimport-local-zone:
  cvsimport: work around perl tzset issue
  git-cvsimport: allow author-specific timezones
Merge branch 'js/hp-nonstop'

Finishing touches to port to HP NonStop continues.

* js/hp-nonstop:
  fix 'make test' for HP NonStop

* mm/maint-doc-commit-edit:
  Document 'git commit --no-edit' explicitly
Merge branch 'mh/strbuf-split'

Cleanups and documentation for strbuf_split.

* mh/strbuf-split:
  strbuf_split*(): document functions
  strbuf_split*(): rename "delim" parameter to "terminator"
  strbuf_split_buf(): simplify iteration
  strbuf_split_buf(): use ALLOC_GROW()
Merge branch 'mh/notes-string-list'

Improve the asymptotic performance of the cat_sort_uniq notes merge
strategy.

* mh/notes-string-list:
  string_list_add_refs_from_colon_sep(): use string_list_split()
  notes: fix handling of colon-separated values
  combine_notes_cat_sort_uniq(): sort and dedup lines all at once
  Initialize sort_uniq_list using named constant
  string_list: add a function string_list_remove_empty_items()
Merge branch 'mg/maint-pull-suggest-upstream-to'

Follow-on to the new "--set-upstream-to" topic from v1.8.0 to avoid
suggesting the deprecated "--set-upstream".

* mg/maint-pull-suggest-upstream-to:
  push/pull: adjust missing upstream help text to changed interface
Merge branch 'jc/prettier-pretty-note'

Emit the notes attached to the commit in "format-patch --notes"
output after three-dashes.

* jc/prettier-pretty-note:
  format-patch: add a blank line between notes and diffstat
  Doc User-Manual: Patch cover letter, three dashes, and --notes
  Doc format-patch: clarify --notes use case
  Doc notes: Include the format-patch --notes option
  Doc SubmittingPatches: Mention --notes option after "cover letter"
  Documentation: decribe format-patch --notes
  format-patch --notes: show notes after three-dashes
  format-patch: append --signature after notes
  pretty_print_commit(): do not append notes message
  pretty: prepare notes message at a centralized place

Start 1.8.1 cycle

Prepare the release notes for the upcoming release, and describe
changes up to the 5th batch we just merged.
