Given the following variables:
* Module A
* Module B
* Model M
* Field X of model M
If module A defines M.X and is installed, an xmlid for this field is
generated in the form of A.field_M_X
Before this commit:
If module B defines M.X as well and is installed after module A, no
xmlid is generated.
This means that if module A is uninstalled, the single xmlid pointing to
M.X will be deleted and thus, the field itself will be deleted as well,
therefore any views from module B referencing M.X will crash.
After this commit:
If module B (or any subsequent modules) define M.X, an xmlid will be
generated in the form of B.field_M_X.
If module A is uninstalled, the xmlid A.field_M_X will be deleted, but
B.field_M_X will remain and thus the field itself won't be deleted.
This system means that for a single actual field, there can be multiple
xmlids, each xmlid sharing the same field, thus the name "shared
fields".
