LU-1842 protocol: add support for OBD_IDX_READ

This patch defines a new RPC format (namely OBD_IDX_READ) which
allows to read the content of an index file via a bulk transfer.
It is simlilar to MDS_READPAGE except that it is not tied to a
specific key/record format (readdir relies on lu_dirent/lu_dirpage).
Like readdir, key/record pairs are stored in a container of a
fixed size (i.e. 4KB) regardless of the client & server page size.

LU-1789 protocol: add support for lightweight connection

A lightweight connection has the following uncommon properties:
- no entry is added to last_rcvd file, so no recovery is possible
- a lightweight connection can be set up while the target is in
  recovery, therefore it should be used use caution
- locks can still be acquired through this connection, although they
  won't be replayed.

We might also consider disabling pings in the future.

LU-1907 build: avoid function resolution mistakes by Coverity

Remove function resolution mistakes made by Coverity version
6.0.3.
The .hs_keycmp function is incorrectly resolved by Coverity,
making the variable passed as its first 'key' parameter to
be considered of the wrong type. Data structures being of
different sizes, it ends up with this Coverity defect:
Out-of-bounds access (OVERRUN_STATIC)
Overrunning static array by passing it as an argument to a
function which indexes it at a higher byte position.
