/*
** Expects pUser to contain fossil user fields in JSON form: name,
** uid, info, capabilities, password.
**
** At least one of (name, uid) must be included. All others are
** optional and their db fields will not be updated if those fields
** are not included in pUser.
**
** If uid is specified then name may refer to a _new_ name
** for a user, otherwise the name must refer to an existing user.
** If uid=-1 then the name must be specified and a new user is
** created (fails if one already exists).
**
** If uid is not set, this function might modify pUser to contain the
** db-found (or inserted) user ID.
**
** On error g.json's error state is set and one of the FSL_JSON_E_xxx
** values from FossilJsonCodes is returned.
**
** On success the db record for the given user is updated.
**
** Requires either Admin, Setup, or Password access. Non-admin/setup
** users can only change their own information. Non-setup users may
** not modify the 's' permission. Admin users without setup
** permissions may not edit any other user who has the 's' permission.
