The `parse_variable` function has two out parameters `var_name` and `var_value`. Currently, those are not being sanitized to `NULL`. when. any error happens inside of the `parse_variable` function. Fix that. While at it, the coding style is improved to match our usual coding practices more closely.

The function `git_config_parse` uses several callbacks to pass data along to the caller as it parses the file. One design shortcoming here is that strings passed to those callbacks are expected to be freed by them, which is really confusing. Fix the issue by changing memory ownership here. Instead of expecting the `on_variable` callbacks to free memory for `git_config_parse`, just do it inside of `git_config_parse`. While this obviously requires a bit more memory allocation churn due to having to copy both name and value at some places, this shouldn't be too much of a burden.

The function to detect a BOM takes an offset where it shall look for a BOM. No caller uses that, and searching for the BOM in the middle of a buffer seems to be very unlikely, as a BOM should only ever exist at file start. Remove the parameter, as it has already caused confusion due to its weirdness.

The function `skip_bom` is being used to detect and skip BOM marks previously to parsing a configuration file. To do so, it simply uses `git_buf_text_detect_bom`. But since the refactoring to use the parser interface in commit 9e66590b (config_parse: use common parser interface, 2017-07-21), the BOM detection was actually broken. The issue stems from a misunderstanding of `git_buf_text_detect_bom`. It was assumed that its third parameter limits the length of the character sequence that is to be analyzed, while in fact it was an offset at which we want to detect the BOM. Fix the parameter to be `0` instead of the buffer length, as we always want to check the beginning of the configuration file.

Currently, the configuration parser will fail reading empty lines with just an CRLF-style line ending. Special-case the '\r' character in order to handle it the same as Unix-style line endings. Add tests to spot this regression in the future.

Upon each line, the configuration parser tries to get either the first non-whitespace character or the first whitespace character, in case there is no non-whitespace character. The logic handling this looks rather odd and doesn't immediately convey this meaning, so add a comment to clarify what happens.

As the config parser is now cleanly separated from the config file code, we can easily refactor the code and make use of the common parser module. This removes quite a lot of duplicated functionality previously used for handling the actual parser state and replaces it with the generic interface provided by the parser context.
Patrick Steinhardt committed -
The configuration file code grew quite big and intermingles both actual configuration logic as well as the parsing logic of the configuration syntax. This makes it hard to refactor the parsing logic on its own and convert it to make use of our new parsing context module. Refactor the code and split it up into two parts. The config file code will only handle actual handling of configuration files, includes and writing new files. The newly created config parser module is then only responsible for parsing the actual contents of a configuration file, leaving everything else to callbacks provided to its provided function `git_config_parse`.
