config_file: properly ignore includes without "path" value
In case a configuration includes a key "include.path=" without any
value, the generated configuration entry will have its value set to
`NULL`. This is unexpected by the logic handling includes, and as soon
as we try to calculate the included path we will unconditionally
dereference that `NULL` pointer and thus segfault.
Fix the issue by returning early in both `parse_include` and
`parse_conditional_include` in case where the `file` argument is `NULL`.
Add a test to avoid future regression.
The issue has been found by the oss-fuzz project, issue 10810.

tests: always unlink created config files
While our tests in config::include create a plethora of configuration
files, most of them do not get removed at the end of each test. This can
cause weird interactions with tests that are being run at a later stage
if these later tests try to create files or directories with the same
name as any of the created configuration files.
Fix the issue by unlinking all created files at the end of these tests.

config_file: refuse modifying included variables
Modifying variables pulled in by an included file currently succeeds,
but it doesn't actually do what one would expect, as refreshing the
configuration will cause the values to reappear. As we are currently not
really able to support this use case, we will instead just return an
error for deleting and setting variables which were included via an
include.

config_file: move reader into `config_read` only
Right now, we have multiple call sites which initialize a `reader`
structure. As the structure is only actually used inside of
`config_read`, we can instead just move the reader inside of the
`config_read` function. Instead, we can just pass in the configuration
file into `config_read`, which eases code readability.

config_file: refresh all files if includes were modified
Currently, we only re-parse the top-level configuration file when it has
changed itself. This can cause problems when an include is changed, as
we were not updating all values correctly.
Instead of conditionally reparsing only refreshed files, the logic
becomes much clearer and easier to follow if we always re-parse the
top-level configuration file when either the file itself or one of its
included configuration files has changed on disk. This commit implements
this logic.
Note that this might impact performance in some cases, as we need to
re-read all configuration files whenever any of the included files
changed. It could increase performance to just re-parse include files
which have actually changed, but this would compromise maintainability
of the code without much gain. The only case where we will gain anything
is when we actually use includes and when only these includes are
updated, which will probably be quite an unusual scenario to actually be
worthwhile to optimize.

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.

Add test for include.path inside included config
It fails at least on my computer, though it may depend on some unpredictable
factors (say, will realloc() extend the memory segment in place, or it will
allocate new memory).

Clean up issues include.path issues found during code review.
* Error-handling is cleaned up to only let a file-not-found error
through, not other sorts of errors. And when a file-not-found
error happens, we clean up the error.
* Test now checks that file-not-found introduces no error. And
other minor cleanups.

Make config reading continue after hitting a missing include file.
For example, if you have
[include]
path = foo
and foo didn't exist, git_config_open_ondisk() would just give up
on the rest of the file. Now it ignores the unresolved include
without error and continues reading the rest of the file.

config: remove the refresh function and backend field
We have been refreshing on read and write for a while now, so
git_config_refresh() is at best a no-op, and might just end up wasting
cycles.

Better search path sandboxing
There are a number of tests that modify the global or system
search paths during the tests. This adds a helper function to
make it easier to restore those paths and makes sure that they
are getting restored in a manner that preserves test isolation.
