t0027: Tests for core.eol=native, eol=lf, eol=crlf

Add test cases for core.eol "native" and "" (unset).
(MINGW uses CRLF, all other systems LF as native line endings)

Add test cases for the attributes "eol=lf" and "eol=crlf"

Other minor changes:
- Use the more portable 'tr' instead of 'od -c' to convert '\n' into 'Q'
  and '\0' into 'N'
- Style fixes for shell functions according to the coding guide lines
- Replace "txtbin" with "attr"

connect: simplify check_ref() using skip_prefix() and starts_with()

Both callers of check_ref() pass in NUL-terminated strings for name.
Remove the len parameter and then use skip_prefix() and starts_with()
instead of memcmp() to check if it starts with certain strings.  This
gets rid of several magic string length constants and a strlen() call.

pack-write: simplify index_pack_lockfile using skip_prefix() and xstrfmt()

Get rid of magic string length constants by using skip_prefix() instead
of memcmp() and use xstrfmt() for building a string instead of a
PATH_MAX-sized buffer, snprintf() and xstrdup().

config: simplify git_config_include()

Instead of using skip_prefix() to check the first part of the string
and then strcmp() to check the rest, simply use strcmp() to check the
whole string.

http-walker: simplify process_alternates_response() using strbuf

Use strbuf to build the new base, which takes care of allocations and
the terminating NUL character automatically.

merge-tree: remove unused df_conflict arguments

merge_trees_recursive() stores a pointer to its parameter df_conflict in
its struct traverse_info, but it is never actually used.  Stop doing
that, remove the parameter and inline the function into merge_trees(),
as the latter is now only passing on its parameters.

Remove the parameter df_conflict from unresolved_directory() as well,
now that there is no way to pass it to merge_trees_recursive() through
that function anymore.

Makefile: propagate NATIVE_CRLF to C

Commit 95f31e9a (convert: The native line-ending is \r\n on MinGW,
2010-09-04) correctly points out that the NATIVE_CRLF setting is
incorrectly set on Mingw git. However, the Makefile variable is not
propagated to the C preprocessor and results in no change. This patch
pushes the definition to the C code and adds a test to validate that
when core.eol as native is crlf, we actually normalize text files to
this line ending convention when core.autocrlf is false.

MinGW: update tests to handle a native eol of crlf

Some of the tests were written with the assumption that the native
eol would always be lf. After defining NATIVE_CRLF on MinGW, these
tests began failing.  This change will update the tests to also
handle a native eol of crlf.

Merge branch 'jc/reopen-lock-file'

There are cases where you lock and open to write a file, close it to
show the updated contents to external processes, and then have to
update the file again while still holding the lock, but the lockfile
API lacked support for such an access pattern.

* jc/reopen-lock-file:
  lockfile: allow reopening a closed but still locked file
Merge branch 'mm/config-edit-global'

Start "git config --edit --global" from a skeletal per-user
configuration file contents, instead of a total blank, when the
user does not already have any.  This immediately reduces the need
for a later "Have you forgotten setting core.user?" and we can add
more to the template as we gain more experience.

* mm/config-edit-global:
  commit: advertise config --global --edit on guessed identity
  home_config_paths(): let the caller ignore xdg path
  config --global --edit: create a template file if needed
Merge branch 'rs/init-no-duplicate-real-path'

* rs/init-no-duplicate-real-path:
  init: avoid superfluous real_path() calls
Merge branch 'ta/config-set'

Add in-core caching layer to let us avoid reading the same
configuration files number of times.

* ta/config-set:
  test-config: add tests for the config_set API
  add `config_set` API for caching config-like files
Merge branch 'jk/pretty-empty-format'

"git log --pretty/format=" with an empty format string did not mean
the more obvious "No output whatsoever" but "Use default format",
which was counterintuitive.

* jk/pretty-empty-format:
  pretty: make empty userformats truly empty
  pretty: treat "--format=" as an empty userformat
  revision: drop useless string offset when parsing "--pretty"
Merge branch 'pr/remotes-in-hashmap'

Optimize remotes configuration look-up in a repository with very
many remotes defined.

* pr/remotes-in-hashmap:
  use a hashmap to make remotes faster
Merge branch 'bc/archive-pax-header-mode'

Implementations of "tar" that do not understand an extended pax
header would extract the contents of it in a regular file; make
sure the permission bits of this file follows the same tar.umask
configuration setting.

* bc/archive-pax-header-mode:
  archive: honor tar.umask even for pax headers
Merge branch 'ta/pretty-parse-config'

* ta/pretty-parse-config:
  pretty.c: make git_pretty_formats_config return -1 on git_config_string failure
Merge branch 'rs/strbuf-getcwd'

Reduce the use of fixed sized buffer passed to getcwd() calls
by introducing xgetcwd() helper.

* rs/strbuf-getcwd:
  use strbuf_add_absolute_path() to add absolute paths
  abspath: convert absolute_path() to strbuf
  use xgetcwd() to set $GIT_DIR
  use xgetcwd() to get the current directory or die
  wrapper: add xgetcwd()
  abspath: convert real_path_internal() to strbuf
  abspath: use strbuf_getcwd() to remember original working directory
  setup: convert setup_git_directory_gently_1 et al. to strbuf
  unix-sockets: use strbuf_getcwd()
  strbuf: add strbuf_getcwd()
