Besides from a general check if a file's directory has write
permissions, this also checks if the directory has set a sticky bit,
meaning that only file owners and the directory owner can remove or move
files in such directory. It's being used in /tmp for example.
About half of the usages were not using `force` anyways, and the other
half presumably just got confused about what "force" really means in
this context (which is "ignore nonexistent files").
The only 'legitimate' user, which is `rm`, instead now handles this
completely internally instead.
`Core::Stream::File` shouldn't hold any utility methods that are
unrelated to constructing a `Core::Stream`, so let's just replace the
existing `Core::File::exists` with the nicer looking implementation.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
We previously had at least three different implementations for resolving
executables in the PATH, all of which had slightly different
characteristics.
Merge those into a single implementation to keep the behaviour
consistent, and maybe to make that implementation more configurable in
the future.
The existing File::is_device() helpers don't distinguish between
block and char devices. This commit adds File::is_block_device() and
File::is_char_device() helpers which are more specific.
This converts the return value of File::read_link() from String to
ErrorOr<String>.
The rest of the change is to support the potential of an Error being
returned and subsequent release of the value when no Error is returned.
Unfortunately at this stage none of the places affected can utililize
our TRY() macro.
Returns the size in bytes for a file path given its filename. Useful
when file size is needed without having to open the file to query it
using fstat() or seeking to the end.
This will generate absolute paths lexically rather than through a call
to realpath. The motivation for this is to generate absolute paths for
non-existent files in unveil calls, as realpath will not work if the
file does not exist.

This was done with the `ambr` search and replace tool.

FileManager, cp, mv, rm had some duplicated code, implementing basic
file management operations. This patch creates adds functions that try
to provide an interface suited for all these programs, but this patch
does not make them be used throughout the Userland.
They are added to Core::File following the example of functions such as
read_link/real_path_for.
