config: implement basic transactional support
When a configuration file is locked, any updates made to it will be done
to the in-memory copy of the file. This allows for multiple updates to
happen while we hold the lock, preventing races during complex
config-file manipulation.

config: write the modified file to memory
Instead of writing into the filebuf directly, make the functions to
write the modified config file write into a buffer which can then be
dumped into the lockfile for committing.
This allows us to re-use the same code for modifying a locked
configuration, as we can simply skip the last step of dumping the data
to disk.

git__tolower: a tolower() that isn't dumb
Some brain damaged tolower() implementations appear to want to
take the locale into account, and this may require taking some
insanely aggressive lock on the locale and slowing down what should
be the most trivial of trivial calls for people who just want to
downcase ASCII.

When writing a configuration file, we want to take a lock on the

(`config`) for reading so that we can prevent somebody from changing

config: write existing lines as-is when rewriting
When updating a configuration file, we want to copy the old data
from the file to preserve comments and funny whitespace, instead
of writing it in some "canonical" format. Thus, we keep a
pointer to the start of the line and the line length to preserve
these things we don't care to rewrite.

config: examine whole file when writing
Previously we would try to be clever when writing the configuration
file and try to stop parsing (and simply copy the rest of the old
file) when we either found the value we were trying to write,
or when we left the section that value was in, the assumption being
that there was no more work to do.
Regrettably, you can have another section with the same name later
in the file, and we must cope with that gracefully, thus we read the
whole file in order to write a new file.
Now, writing a file looks even more than reading. Pull the config
parsing out into its own function that can be used by both reading
and writing the configuration.

If git_config_delete is to work properly in the presence of duplicate section

there may be another matching section later.

when the desired key is found or there are no sections left to parse.

config: borrow refcounted references
This changes the get_entry() method to return a refcounted version of
the config entry, which you have to free when you're done.
This allows us to avoid freeing the memory in which the entry is stored
on a refresh, which may happen at any time for a live config.
For this reason, get_string() has been forbidden on live configs and a
new function get_string_buf() has been added, which stores the string in
a git_buf which the user then owns.
The functions which parse the string value takea advantage of the
borrowing to parse safely and then release the entry.

For example, if you have

without error and continues reading the rest of the file.

config: a multiline var can start immediately
In the check for multiline, we traverse the backslashes from the end
backwards and int the end assert that we haven't gone past the beginning
of the line. We make sure of this in the loop condition, but we also
check in the return value.
However, for certain configurations, a line in a multiline variable
might be empty to aid formatting. In that case, 'end' == 'start', since
we ended up looking at the first char which made it a multiline.
There is no need for the (end > start) check in the return, since the
loop guarantees we won't go further back than the first char in the
line, and we do accept the first char to be the final backslash.
This fixes #2483.

With the isolation of complex reads, we can now try to refresh the

refreshed. This is no longer the case, as a read can also invalidate the
pointer.

In order to have consistent views of the config files for remotes,

The goal here is to provide the snapshotting part by creating a
read-only copy of the state of the configuration at a particular point
in time, which does not change when a repository's main config changes.

Add config read fns with controlled error behavior
This adds `git_config__lookup_entry` which will look up a key in
a config and return either the entry or NULL if the key was not
present. Optionally, it can either suppress all errors or can
return them (although not finding the key is not an error for this
function). Unlike other accessors, this does not normalize the
config key string, so it must only be used when the key is known
to be in normalized form (i.e. all lower-case before the first dot
and after the last dot, with no invalid characters).
This also adds three high-level helper functions to look up config
values with no errors and a fallback value. The three functions
are for string, bool, and int values, and will resort to the
fallback value for any error that arises. They are:
* `git_config__get_string_force`
* `git_config__get_bool_force`
* `git_config__get_int_force`
None of them normalize the config `key` either, so they can only
be used for internal cases where the key is known to be in normal
format.

Fix saving remotes with several fetch/push ref specs.
At some moment git_config_delete_entry lost the ability to delete one entry of
a multivar configuration. The moment you had more than one fetch or push
ref spec for a remote you will not be able to save that remote anymore. The
changes in network::remote::remotes::save show that problem.
I needed to create a new git_config_delete_multivar because I was not able to
remove one or several entries of a multivar config with the current API.
Several tries modifying how git_config_set_multivar(..., NULL) behaved were
not successful.
git_config_delete_multivar is very similar to git_config_set_multivar, and
delegates into config_delete_multivar of config_file. This function search
for the cvar_t that will be deleted, storing them in a temporal array, and
rebuilding the linked list. After calling config_write to delete the entries,
the cvar_t stored in the temporal array are freed.
There is a little fix in config_write, it avoids an infinite loop when using
a regular expression (case for the multivars). This error was found by the
test network::remote::remotes::tagopt.

Merge git_buf and git_buffer
This makes the git_buf struct that was used internally into an
externally available structure and eliminates the git_buffer.
As part of that, some of the special cases that arose with the
externally used git_buffer were blended into the git_buf, such as
being careful about git_buf objects that may have a NULL ptr and
allowing for bufs with a valid ptr and size but zero asize as a
way of referring to externally owned data.

config: allow empty string as value
`git_config_set_string(config, "config.section", "")` fails when
escaping the value.
The buffer in `escape_value` is allocated without NULL-termination. And
in case of empty string 0 is passed for buffer size in `git_buf_grow`.
`git_buf_detach` returns NULL when the allocated size is 0 and that
leads to an error return in `GITERR_CHECK_ALLOC` called after
`escape_value`
The change in `config_file.c` was suggested by Russell Belfer <rb@github.com>

replaced foreach() with non callback based iterations in git_config_backend
new functions in struct git_config_backend:
* iterator_new(...)
* iterator_free(...)
* next(...)
The old callback based foreach style can still be used with `git_config_backend_foreach_match`

added new type and several functions to git_strmap
This step is needed to easily add iterators to git_config_backend
As well use these new git_strmap functions to implement foreach
* git_strmap_iter
* git_strmap_has_data(...)
* git_strmap_begin(...)
* git_strmap_end(...)
* git_strmap_next(...)

Typedef git_config_level_t and use it everywhere
The GIT_CONFIG_LEVEL constants actually work well as an enum
because they are mutually exclusive, so this adds a typedef to
the enum and uses that everywhere that one of these constants are
expected, instead of the old code that typically used an unsigned
int.

Move git_config_backend to include/git2/sys
Moving backend implementor objects into include/git2/sys so the
APIs can be isolated from the ones that normal libgit2 users
would be likely to use.

Implement config key validation rules
This is a new implementation of core git's config key checking
rules that prevents non-alphanumeric characters (and '-') for
the top-level section and key names inside of config files.
This also validates the target section name when renaming
sections.

config: support trailing backslashes
Check whether the backslash at the end of the line is being escaped or
not so as not to consider it a continuation marker when it's e.g. a
Windows-style path.

Consolidate text buffer functions
There are many scattered functions that look into the contents of
buffers to do various text manipulations (such as escaping or
unescaping data, calculating text stats, guessing if content is
binary, etc). This groups all those functions together into a
new file and converts the code to use that.
This has two enhancements to existing functionality. The old
text stats function is significantly rewritten and the BOM
detection code was extended (although largely we can't deal with
anything other than a UTF8 BOM).
