test-dispatch: make the test compatible with chg The test is broken when run with chg because it prints a different error message when chg is running. This commit fixes the test by special casing for chg. Test Plan: Ran the test 'test-dispatch.t' with and without '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1126

histedit: remove the nonexistant config 'histeditng' D942 removed the experimental config 'histeditng'. This is a leftover which should have been removed in that commit. Therefore, this commit completes the cleanup. Test Plan: Ran all the tests. Differential Revision: https://phab.mercurial-scm.org/D1123

context: add workingfilectx.markcopied With in-memory merge, copy information needs to be stored in-memory, not in the dirstate. To make this transition easy, move the existing dirstate-based approach to workingfilectx; that way, other implementations can choose to store it somewhere else.

merge: don't use workers in in-memory mode The worker processes can't share memory, so workers should not be used. Differential Revision: https://phab.mercurial-scm.org/D1105

filemerge: use arbitraryfilectx for backups With in-memory merge, backup files might be overlayworkingfilectxs stored in memory. But they could also be real files if the user's backup directory is outside the working dir. Rather than have two code paths everywhere, let's use arbitraryfilectx so they can be consistent.

registrar: add support for storing the type of command in func object This patch adds support for storing the type of command which is going to run in the func object. For this it does the following: 1) Add three possible values as attributes to the registrar.command class 2) Add a new argument to registrar.command._doregister function 3) Add a new attribute cmdtype to the func object The type of command will be helpful in deciding what level of access on hidden commits it can has.

releasenotes: fix documentation of similaritycheck() The function document says that it returns true when the fragment can be merged, but if you see the function just above it which is similar(), it writes already exists thing if return value from similaritycheck() is False which is just opposite of the doc. This patch fixes that. Differential Revision: https://phab.mercurial-scm.org/D1119
