This is a deviation from the Posix readlink function that from my
point of view makes this function easier to use. In Posix, probably
the assumption is that readlink is cheap, so someone under memory
constraints could just start with a small buffer and incrementally
increase the buffer size. For us, it's a network round-trip, and we
have the luxury of [mt]alloc, which the syscall kernel interface does
not have.

From my point of view the option to change "cli" between
cli_posix_readlink_send and _recv is not necessary.

This moves the parsing work from the _recv function into the _done
function. This makes writing the SMB2 call easier later on: We can
have a smb2-specific done function doing the smb2-specific work and we
don't have to fork on protocol in the _recv function.

cli_read_sink() and pull_helper() were essentially identical. By making
cli_read_sink() non-static, we can delete the latter.

So far only cli_pull could be called directly without looking at the

This can be used temporarily to do the required kinit if we use kerberos
and the password has been specified.
In future this should be done in the gensec layer on demand, but there's
more work attached to doing it in the gensec_gse module.

This can be used with a valid creds structure in order
to do a share level authentication or with NULL in the cases
we assume a modern server already.
Later we can change the ordering and implement

Note: This has *NO* effect on the lock context code, as on the
wire for all SMB1 locking requests, the pid used as the lock
context is already truncated down to 16-bits - the field is only
16-bits wide.
This allows the cli_XXX() calls to correctly set pidlow AND pidhigh
in SMB1 requests put on the wire by the libcli/smb/smb1*.c code.
Note that currently the smbd server doesn't correctly return
pidhigh yet - a fix (and tests) for that will follow.
As pidhigh is not checked in any client code (mid is used
to differentiate different requests) this has no effect
other than a correctness fix.
