Heschi Kreinick 416e8f4faf internal/imports: require valid options, move LocalPrefix up ... CL 239754 eagerly initialized the environment. This turns out to be a problem for gopls, which calls ApplyFixes with no ProcessEnv. Reinitializing it every time seriously harmed the performance of unimported completions. Move back to lazy initialization. Working with invalid options has caused a lot of confusion; this is only the most recent. We have to maintain backwards compatibility in the externally visible API, but everywhere else we can require fully populated options. That includes the source byte slice and the options. LocalPrefix is really more of an Option than an attribute of the ProcessEnv, and it is needed in ApplyFixes where we really don't want to have to pass a ProcessEnv. Move it up to Options.
