Before switching to using DocumentChannel to process multipart requests, multipart documents loaded as a view-source load would be displayed their plain-text data, as the multipart processing would be after the view-source channel had wrapped the channel, and replaced the content type with "application/x-view-source". This change restores that behaviour, by preventing parent process multipart processing for wrapped channels like `view-source` loads. This also allowed removing the replaceRequest option on nsViewSourceChannel, as it was no longer necessary, and required introducing a mechanism to get the inner http channel for process switching. The crash in Bug 1670530 was caused by a bad interaction between the view-source replaceChannel logic, and the parent/content process switching logic, which could lead to the load in the content process being initialized in a broken state after a process switch, due to accidentally acting on a wrapped view-source channel when an unwrapped one was expected. This patch also fixes that issue, by removing the replaceRequest logic which caused it in the first place. Differential Revision: https://phabricator.services.mozilla.com/D98205
