A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.
Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).
This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).

When 473166b (config: add 'origin_type' to config_source
struct, 2016-02-19) added accessor functions for the origin
type and name, it taught them only to look at the "cf"
struct that is filled in while we are parsing the config.
This is sufficient to make it work with git-config, which
uses git_config_with_options() under the hood. That function
freshly parses the config files and triggers the callback
when it parses each key.
Most git programs, however, use git_config(). This interface
will populate a cache during the actual parse, and then
serve values from the cache. Calling current_config_filename()
in a callback here will find a NULL cf and produce an error.
There are no such callers right now, but let's prepare for
adding some by making this work.
We already record source information in a struct attached to
each value. We just need to make it globally available and
then consult it from the accessor functions.

When we parse a config file, we set up the global "cf"
variable as a pointer to a "struct config_source" describing
the file we are parsing. This is used for error messages, as
well as for lookup functions like current_config_name().
The "cf" variable is NULL in two cases:
1. When we are parsing command-line config, in which case
there is no source file.
2. When we are not parsing any config at all.
Callers like current_config_name() must assume we are in
case 1 if they see a NULL "cf". However, this means that if
they are accidentally used outside of a config parsing
callback, they will quietly return a bogus answer.
This might seem like an unlikely accident (why would you ask
for the current config file if you are not parsing config?),
but it's actually an easy mistake to make due to the
configset caching. git_config() serves the answers from a
configset cache, and any calls to current_config_name() will
claim that we are parsing command-line config, no matter
what the original source.
So let's distinguish these cases by having the command-line
config parser set up a config_source with a NULL name (which
callers already handle properly). We can use this to catch
programming errors in some cases, and to give better
messages to the user in others.

We have several exits from the function, each of which has
to do some cleanup. Let's consolidate these in an "out"
label we can jump to. This doesn't save us much now, but it
will help as we add more things that need cleanup.

Prior to 1f2baa7 (config: treat non-existent config files as
empty, 2010-10-21), we returned an error if any config files
were missing. That commit made this a non-error, but
returned the number of sources found, in case any caller
wanted to distinguish this case.
In the past 5+ years, no caller has; the only two places
which bother to check the return value care only about the
error case. Let's drop this code, which complicates the
function. Similarly, let's drop the "found anything" return
from git_config_from_parameters, which was present only to
support this (and similarly has never had other callers care
for the past 5+ years).
Note that we do need to update a comment in one of the
callers, even though the code immediately below it doesn't
care about this case.

"git commit --dry-run" reported "No, no, you cannot commit." in one
case where "git commit" would have allowed you to commit, and this

not give you the correct answer, for example). This is a stop-gap
measure in that "commit --short --dry-run" still gives an incorrect
result.
