* tools/libbpf: support bigger BTF data sizes

While it's understandable why kernel limits number of BTF types to 65535
and size of string section to 64KB, in libbpf as user-space library it's
too restrictive. E.g., pahole converting DWARF to BTF type information
for Linux kernel generates more than 3 million BTF types and more than
3MB of strings, before deduplication. So to allow btf__dedup() to do its
work, we need to be able to load bigger BTF sections using btf__new().

8e42f42533 scripts: add script to sync kernel changes (#13) 
This script automates the process of applying libbpf-relevant changes
from kernel repository on top of current state of libbpf repository.

It uses CHECKPOINT-COMMIT file to keep track of last commit in kernel
repo up to which libbpf is in sync with. If there are any new libbpf
changes in kernel repository, script extracts them, preserving original
commit metadata. It also creates a "sync commit" using cover letter as
a template, which nicely summarizes changes since last sync with kernel.

Usage: ./scripts/sync-kernel.sh <linux-repo> <libbpf-repo>

If it succeeds, script will create a bunch of local commits in
<libbpf-repo> in separate branch, which can be easily pushed into github
to create a pull request.

Script tries to clean up after itself, except in case of failure. But it
doesn't clean up timestamped branches it creates in both kernel and
libbpf repositories for now. We can add that later.
