dispatch: making all hg abortions be output with a specific label This allows abortions to be highlighted specially and separately from warnings - for instance, red is a reasonable color for when hg aborts, but is overly dramatic for most warnings produced elsewhere.

ui: fix implicit unicode-to-bytes conversion introduced in 9df29b7c62cf This is harmless, unless you try and run hg with HGUNICODEPEDANTRY enabled. It's technically wrong, so let's go ahead and fix it. Differential Revision: https://phab.mercurial-scm.org/D3989

lfs: avoid a potential variable reference before assignment error in cmdserver A coworker hit this once yesterday when pulling in thg (a retry worked), and then I hit it with strip after a pull. I had a difficult time recreating a test for this (at least one of the tricks was to not use '-R', which seems to cause reposetup() to be called for each command), so I'm not sure how large of a window there actually is for this. Calling reposetup() *after* the requirement is added will skip the hook entirely. The other issue I had was adding a couple `ui.status()` lines around the check that installs the hook. On Windows, the cmdserver process ballooned to 1.6GB and hung. Changing that to `ui.warn()` avoided the hang. It also hung on macOS, but without the large memory usage.

manifest: fix out-of-bounds read of corrupted manifest entry Spotted by ASAN.

manifest: rewrite pathlen() to not cross entry boundary Even though the entire manifest data should be terminated by '\0', it seems not nice to scan '\0' over the entry terminator, '\n'.

chgserver: do not send system() back to client if stdio redirected (issue5992) As the chg client doesn't know server-side stdio redirection, the server shouldn't upcall on "runsystem" request if the stdio streams are redirected. This patch teaches ui to remember the redirection flag, which is updated by the caller right now. Future patches (for default) will add ui methods to manage this flag internally.

chgserver: update comment describing when to fall back to core _runsystem() The condition "output needs to be captured" was moved to the core ui, and removed at fbce78c58f1e "chg: refactor ui.system() to be partly overridden." The next patch will add one more "if" to address the issue 5992.
