Until all callers are fixed to pass the same 'server_computer'
value, we try to calculate a server_netbios_name and use this
as unique identifier for a specific domain controller.
Otherwise winbind would use 'hostname.example.com'
while 'net rpc testjoin' would use 'HOSTNAME',
which leads to 2 records in netlogon_creds_cli.tdb
for the same domain controller.
Once all callers are fixed we can think about reverting this
commit.

This provides an abstraction to hide netlogon_creds_CredentialState,
which is stored in a node local tdb.
Where the global state (netlogon_creds_CredentialState) between client and
server was only kept in memory (on the client side), we now use
the abstracted netlogon_creds_cli_context.
We now use a node specific computer name in order to establish
individual netlogon sessions per node.
If the caller wants to use some netlogon calls with credential chain
(struct netr_Authenticator), netlogon_creds_cli_lock*() is used
to get the current netlogon_creds_CredentialState in a g_lock'ed
fashion, a talloc_free() will release the lock.
The locking is needed as there might be more than one process
(multiple winbindd child, cmdline tools) which want to talk
to a specific domain controller. The usage of netlogon_creds_CredentialState
needs to be serialized as it uses sequence numbers.
LogonSamLogonEx doesn't use the credential chain, but for some operations
it needs the global session in order to de/encrypt individual fields.
It uses the lockless netlogon_creds_cli_get() and netlogon_creds_cli_validate()
functions, which just make sure the session hasn't changed between
get and validate.
This is prepares the proper fix for a large number of bugs:

This changes (again...) our system md5 detection to cope with how
OpenIndiana does md5. I'm becoming increasingly convinced this isn't
worth our while (we should have just done samba_md5...), but for now
this change seems to work on FreeBSD, OpenIndiana and Linux with
libbsd.
This needs us to rename struct MD5Context -> MD5_CTX, but we provide a
config.h define to rename the type bad if MD5_CTX does not exist (it does
however exist in the md5.h from libbsd).

This removes special-case for initalising the children array in
insert_in_object_tree(). talloc_realloc() handles the intial allocate
case perfectly well, so there is no need to have this duplicated.
This also restores having just one place were the rest of the elements
are intialised, to ensure uniform behaviour.
To do this, we have to rework insert_in_object_tree to have only one
output variable, both because having both root and new_node as output
variables was too confusing, and because otherwise the two pointers
were being allowed to point at the same memory.
