Due to the preconditions, there should never be an error, but it pays
to be paranoid.

There is no need to keep config file in memory until the the
configuration is freed. Free the buffer immediately after the
configuration has been parsed.

Make cvar_name_match really compare the last part of the variable

If a variable is on its own, truth should be assumed. Check this is
true in our code.

If a variable name appears on its own in a line, it's assumed the
value is true. Store the variable name as NULL in that case.

These tests are basic, but they should tell us when we've broken
something.

If a line ends at EOF there is no need to check for the newline
character and doing so will cause us to read memory beyond the
allocatd memory as we check for the Windows-style new-line, which is
two bytes long.

If a variable value has the traditional continuation character (\) as
the last non-space character in the line, then we continue reading the
value on the next line.

Using more than two lines is also supported.

Make header and variable parse functions use their own buffers instead
of giving them the line they need to read as a parameter which they
mostly ignore.

This is in preparation for multiline configuration variables.

On error, the buffer containing the file contents also needs to be
freed.

The git test repository was holding a wrongly named tag reference ("very-simple") pointing at a tag named "e90810b".
This mistake (mine :-/ ) originates back to https://github.com/libgit2/libgit2/commit/9282e92

Whole credit goes to @tclem for having spotted this.

Streaming writes will no longer fail when writing to a backend that
doesn't support streaming writes but supports direct ones.
Now we create a fake stream on memory and then write it as a single
block using the backend `write` callback.

Creates a tree by scanning the index file. The method handles recursive
creation of trees for subdirectories and adds them to the parent tree.

A variable name is stored internally with its section the way it
appeared in the configuration file in order to have the information
about what parts are case-sensitive inline.

Really implement parse_section_header_ext and move the assignment of
variables to config_parse.

The variable name matching is now done in a case-away way by
cvar_name_match and cvar_section_match. Before the user sees it, it's
normalized to the two- or three-dot version.

If we want debugging symbols, we most likely want them to point to the
right place. With -O2, gdb or valgrind may give wrong information.
