bcc3bddcf4 filter: only check whether a child path could match when necessary
When checking excludes there is no need to test whether a child path
could also match the pattern, as it is by definition excluded.
Previously childMayMatch was calculated but then discarded. For simple
absolute paths this can account for half the time spent for checking
pattern matches.

This only allocates a single slice to expand the double wildcard and

40ee17167e local: Ignore permission errors on chmod call in Save/Remove operation
The file is already created with the proper permissions, thus the chmod
call is not critical. However, some file systems have don't allow
modifications of the file permissions. Similarly the chmod call in the Remove
operation should not prevent it from working.

673dda77c0 Less repetitive error messages in internal/cache
Many instances of errors.Wrap in this package would produce messages
like "Open: open <filename>: no such file or directory"; those now omit
the first "Open:" (or "Stat:", or "MkdirAll"). The function readVersion
now appends its own name to the error message, rather than the function
that failed, to make it easier to spot. Other function names (e.g.,
Load) are already added further up in the call chain.

c4e2203e45 Check error in archiver before calling Select
The archiver first called the Select function for a path before checking
whether the Lstat on that path actually worked. The RejectFuncs in
exclude.go worked around this by checking whether they received a nil
os.FileInfo. Checking first is more obvious and requires less code.

Don't require self-update --output placeholder file
This removes the requirement on `restic self-update --output` to point
to a path of an existing file, to overwrite. In case the specified
path does exist we still want to verify that it's a regular file,
rather than a directory or a device, which gets overwritten.

We also want to verify that a path to a new file exists within an
existing directory. The alternative being running into that issue
after the actual download, etc has completed.

While at it I also replace `errors.Errorf` with the more appropriately
verbose `errors.Fatalf`.
