3706b27a3b libcli/smb: prepare support for SMB2_SIGNING_CAPABILITIES negotiation 
For now client_sign_algos->num_algos will always be 0,
but that'll change in the next commits.

9e6d3df68d libcli/smb: add smb311_capabilities_check() helper 
It checks that the resulting algorithms (most likely for
dialects < 3.1.1) are actually allowed.

147dd9d58a libcli/smb: let smb2_negotiate_context_parse() only parse the expected number of contexts 
Any garbage at the end needs to be ignored.

This fixes the Negotiate_SMB311_ContextID_NetName test from:
https://github.com/microsoft/WindowsProtocolTestSuites/blob/main/TestSuites/FileServer/src/SMB2/TestSuite/Negotiate/Negotiation.cs#L730

e8e9677154 libcli: Pass buf/len to smb2_negotiate_context_add 
Every caller did a data_blob_const() right before calling
smb2_negotiate_context_add(). Avoid that.
