This patch adds array support to btf_struct_access(). It supports array of int, array of struct and multidimensional array. It also allows using u8[] as a scratch space. For example, it allows access the "char cb[48]" with size larger than the array's element "char". Another potential use case is "u64 icsk_ca_priv[]" in the tcp congestion control. btf_resolve_size() is added to resolve the size of any type. It will follow the modifier if there is any. Please see the function comment for details. This patch also adds the "off < moff" check at the beginning of the for loop. It is to reject cases when "off" is pointing to a "hole" in a struct.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
