Add a --validate flag to pyynl for explicit schema check with error
reporting and add a schema_check make target to check all YNL specs.

When listing attributes with --list-attrs, display the actual enum
values for attributes that reference an enum type.
# ./cli.py --family netdev --list-attrs dev-get
[..]
- xdp-features: u64 (enum: xdp-act)
Flags: basic, redirect, ndo-xmit, xsk-zerocopy, hw-offload, rx-sg, ndo-xmit-sg
Bitmask of enabled xdp-features.

Enhance the --list-attrs option to recursively display nested attributes
instead of just showing "nest" as the type.
Nested attributes now show their attribute set name and expand to
display their contents.
# ./cli.py --family ethtool --list-attrs rss-get
[..]
Do request attributes:
- header: nest -> header
- dev-index: u32
- dev-name: string
- flags: u32 (enum: header-flags)
- phy-index: u32
- context: u32

Add a --list-attrs option to the YNL CLI that displays information about
netlink operations, including request and reply attributes.
This eliminates the need to manually inspect YAML spec files to
determine the JSON structure required for operations, or understand the
structure of the reply.
Example usage:
# ./cli.py --family netdev --list-attrs dev-get
Operation: dev-get
Get / dump information about a netdev.
Do request attributes:
- ifindex: u32
netdev ifindex
Do reply attributes:
- ifindex: u32
netdev ifindex
- xdp-features: u64 (enum: xdp-act)
Bitmask of enabled xdp-features.
- xdp-zc-max-segs: u32
max fragment count supported by ZC driver
- xdp-rx-metadata-features: u64 (enum: xdp-rx-metadata)
Bitmask of supported XDP receive metadata features. See Documentation/networking/xdp-rx-metadata.rst for more details.
- xsk-features: u64 (enum: xsk-flags)
Bitmask of enabled AF_XDP features.
Dump reply attributes:
- ifindex: u32
netdev ifindex
- xdp-features: u64 (enum: xdp-act)
Bitmask of enabled xdp-features.
- xdp-zc-max-segs: u32
max fragment count supported by ZC driver
- xdp-rx-metadata-features: u64 (enum: xdp-rx-metadata)
Bitmask of supported XDP receive metadata features. See Documentation/networking/xdp-rx-metadata.rst for more details.
- xsk-features: u64 (enum: xsk-flags)
Bitmask of enabled AF_XDP features.

We default to raising an exception when unknown attrs are found
to make sure those are noticed during development.
When YNL CLI is "installed" and used by sysadmins erroring out
is not going to be helpful. It's far more likely the user space
is older than the kernel in that case, than that some attr is
misdefined or missing.

When sending YNL CLI output into a pipe, closing the pipe causes a
BrokenPipeError. E.g. running the following and quitting less:
./tools/net/ynl/pyynl/cli.py --family rt-link --dump getlink | less
Traceback (most recent call last):

BrokenPipeError: [Errno 32] Broken pipe
Consolidate the try block for ops and notifications, and gracefully
handle the BrokenPipeError by adding an exception handler to the
consolidated try block.

Add a --family option to ynl to specify the spec by family name instead
of file path, with support for searching in-tree and system install
location and a --list-families option to show the available families.
./tools/net/ynl/pyynl/cli.py --family rt_addr --dump getaddr

Move python code to a separate directory so it can be
packaged as a python module. Updates existing references
in selftests and docs.
Also rename ynl-gen-[c|rst] to ynl_gen_[c|rst], avoid
dashes as these prevent easy imports for entrypoints.
