This is a preparatory step to making `get()` return `ErrorOr`.
|
|
This generally seems like a better name, especially if we somehow also
need a better name for "read the entire buffer, but not the entire file"
somewhere down the line.

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 :^)

The variable `print_verbose` (which prints verbose information about the
USB devices connected to the system) was uninitialized in `lsusb`. This
was causing the verbose information to be printed if `-v` was NOT seen
on the command line.
|
|
In case we failed to open /res/usb.ids or the user requested to not use
that file, we simply don't try to resolve the USB IDs and print them
without any identification.

Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
|
|
We can now get a more verbose print out from `lsusb` that spits out all
of the devices descriptors :^)

Also add slightly richer parse errors now that we can include a string
literal with returned errors.
This will allow us to use TRY() when working with JSON data.
|
|
We now expose the `USBDevice`'s address in the SysFS object. This means
that device addresses are no longer determined by the name of the file
in the `/bus/usb/` directory. This was an incorrect way of determining
device address, as a standard PC can have multiple USB controllers
(and hence multiple buses) that can have overlapping device IDs.
|
|
This patch moves all the USB data from /proc/bus/usb to /sys/bus/usb.

Simple clone of LibPCIDB to support USB IDs instead of PCI
ones. The format is basically identical, besides a few changes
of the double tab fields.
