yanglint FEATURE schema mount support (#1901)
* modify existing context if provided
In ly_ctx_new_yldata(), check if *ctx is NULL. If so, proceed as before
with allocating a new context. Otherwise, load modules into the existing
context.

* add parent-reference xpath helper to schema-mount plugin
This new function produces a list of schema nodes from the expanded
parent-reference xpath expressions.

* add context lookup to schema-mount plugin
This function allocates a new context for a particular instance of the
yangmnt:mount-point extension.

* yanglint: schema-mount extension callback
Add a commandline argument "-x" that accepts a file containing extension
data, used to create a context for the schema-mount extension. This file
has the same format as what is provided to the "-Y" option. A callback
function for the schema-mount extenion is registered if the new option
is specified.
This allows validating instance data for models that include a schema
mount point.

* yanglint: print mounted schema trees
Display "mp" flag for mount point and print mounted tree. Also display
the / and @ opts in node names.
