When a text file with mixed line endings is commited into the repo,
it is called "not normalized" (or NNO) in t0027. The existing test
case using repoMIX did not fully test all combinations: (Especially
when core.autocrlf = true) Files with NL are not converted at
commit, but at checkout, so a warning NL->CRLF is given. Files with
CRLF are not converted at all (so no warning will be given), unless
they are marked as "text" or "auto".
Remove repoMIX introduced in commit 8eeab92f02, and replace it with
a combination of NNO tests.

"new safer autocrlf handling":
- Check if eols in a file are converted at commit, when the file has
CR (or CRLF) in the repo (technically speaking in the index).
- Add a test-file repoMIX with mixed line-endings.
- When converting LF->CRLF or CRLF->LF: check the warnings
checkout_files():
- Checking out CRLF_nul and checking for eol coversion does not
make much sense (CRLF will stay CRLF).
- Use the file LF_nul instead: It is handled a binary in "auto" modes,
and when declared as text the LF may be replaced with CRLF, depending
on the configuration.

t0027 expects the native end-of-lines to be a single line feed
character. On Windows, however, we set it to a carriage return
character followed by a line feed character. Thus, we have to
modify t0027 to expect different warnings depending on the
end-of-line markers.
Adjust the check of the warnings and use these macros:
WILC: Warn if LF becomes CRLF
WICL: Warn if CRLF becomes LF
WAMIX: Mixed line endings: either CRLF->LF or LF->CRLF
Improve the information given by check_warning().
Use test_cmp to show which warning is missing (or shouldn't be
there).

Make more clear what the tests are doing:
commit_check_warn():
Commit files and checks for conversion warnings.
Old name: create_file_in_repo()
checkout_files():
Checkout files from the repo and check if they have
the appropriate line endings in the work space.
Old name: check_files_in_ws()
Replace non-leading TABS with spaces

Depending on the file content, eol parameters and .gitattributes
"git add" may give a warning when the eol of a file will change when
the file is checked out again.
There are 2 different warnings, either "CRLF will be replaced..." or
"LF will be replaced...". Let t0027 check for these warnings by
adding new parameters to create_file_in_repo(), which tells what
warnings are expected.
When a file has eol=lf or eol=crlf in .gitattributes, it is handled
as text and should be normalized. Add tests for these cases that
were not covered.

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"

Historically there are 3 different parameters controlling how line endings
are handled by Git:
- core.autocrlf
- core.eol
- the "text" attribute in .gitattributes
There are different types of content:
- (1) Files with only LF
- (2) Files with only CRLF
- (3) Files with mixed LF and CRLF
- (4) Files with LF and/or CRLF with CR not followed by LF
- (5) Files which are binary (e.g. have NUL bytes)
Recently the question came up, how files with mixed EOLs are handled by Git
(and libgit2) when they are checked out and core.autocrlf=true.

Add the EXPENSIVE t0027-auto-crlf.sh to test all combination of files
and parameters for both "git add/commit" and "git checkout".
