We had a few places where we had perhaps too much of an opinion on the
permissions on created files and directories, sometimes fuled by a
misconception about how permissions work in both Unix and Windows. Recap
on the ground rules:
- On all unixes, all file & directory creation (`Mkdir`, `MkdirAll`,
`Create`, `WriteFile`, `Open`) has the given permission bits filtered
via the user's umask. The proper permissions for us to use are in almost
all cases 0o666 for files and 0o777 for directories, strange as that may
look at the call site.
- On Windows, there is no umask but in turn all of the permission bits
except the user write bit are ignored. The absence of user write bit is
converted into the read only attribute. This means that what is proper
for Unix above is also proper for Windows.
- We make an exception when creating files for certificate keys and the
config / database directories, as those contain secrets we think should remain closed
even if the user generally collaborates with other users on the system.
(Also removal of a bugfixed copy of MkdirAll for Windows that hasn't
been necessary for a few years.)

Fix a response body leak in `githubSourceCodeLoader.Load` where the body
was not closed when the HTTP status was non-200.

lib/ur brings in a lot of dependencies we don't need in e.g.
stcrashreceiver, who only needs the small failure reporting structs.
Make those part of the lean `contract` package instead.

The runtime prints a lot of context for crashes due to bad pointers etc,
which is required to understand the crash, but this context comes before
the `fatal error: ...` line. Currently those lines get filtered out and
not included in the crash report. This change modifies the criteria so
that we start collecting crash data also at a line that begins with
`runtime:`, and tweaks the parsing later to look for the specific
`panic:` or `fatal error:` which may come later as the subject.

The sort package is still used in places that were not trivial to
change. Since Go 1.21 slices package can be uswed for sort. See
https://go.dev/doc/go1.21#slices
### Purpose
Make some progress with the migration to a more up-to-date syntax.
Move infrastructure related commands to under `cmd/infra` and
development stuff to `cmd/dev`. The default build command builds the
regular user facing binaries: syncthing, stdiscosrv, and strelaysrv.
