Pay down technical debt

[dscho]

This is a meta work item, really: I spent some two days last week to perform a merging-rebase of our master onto itself, with the sole purpose of reordering patches/patch series into a shape that allows us to know exactly where we are with the patches. One outcome is the ready-for-upstream branch thicket, combining all of the patch series I deem ready for upstream. Here is the check list (the idea being to check every patch series as it is chomped off the list):

• mingw-isatty-and-dup2
• mingw-expand-absolute-user-path
• mingw-git.res-bitness
• mingw-load-sys-dlls
• test-git-installed
• fix-gc-segfault
• azure-pipelines
• mingw-CreateHardLink
• require-windows-vista-or-later
• file-url-to-unc-path
• http-ssl-backend
• bw/config-h
• test-unc-fetch
• unc-path-w-backslashes
• release-gc-repack
• drive-prefix
• case-insensitive-abspath
• jeffhostetler/register_rename_src
• gitdir-at-unc-root
• test-unc-alternates
• mingw-safer-compat-poll
• create-empty-bundle
• unmask-credentials-username
• aslr
• mingw-getcwd
• sideband-bug
• fix-externals
• remote-hg-prerequisites
• add-e-truncate
• cvsexportcommit-crlf
• reset-stdin
• unhidden-git
• perl5lib
• mingw-modernize-pthread_cond_t
• default-ident

I added GitGitGadget PRs for all of the branches in ready-for-upstream and am slowly submitting them. So let's close this here ticket, as the individual progress is tracked in those PRs.
