farewell, gotweb. you served us well. rm gotweb, ok stsp@

enforce a per-uid connection limit in the gotd listen process For now the limit is set at compile-time. It will become configurable via gotd.conf soon. ok op@

gotwebd: drop redundant NULL check qs is guaranteed to be not NULL reached that point.

gotwebd: remove useless comment should be placed further down, after BLOB and RSS are handled, but the call to `gotweb_render_header' is successfully clear on its own.

gotd listen process forgot to initialize its client table siphash key

convert gotd repo_read.c and repo_write.c to single-client Because these processes are now started on demand per client connection there is no need to keep track of multiple clients anymore. Also, these processes can now exit when a disconnect event is received. ok op, jamsek

gotd: nix trailing whitespace and indentation fix ok op@, stsp@

remove filesystem access via bind(2) from gotd auth process op@ pointed out a problem in my initial patch where I forgot to call unveil(2) with a path before unveil(NULL, NULL). ok op, jamsek

move "unix" pledge promise from gotd parent to auth process The listen process now communicates the client UID/GID to the parent, and the auth process verifies this on behalf of the parent. This allows us to remove the "unix" pledge promise from the parent, removing parent access to syscalls such as listen() and accept() in the AF_UNIX domain. ok tracey@ op@

fix gotd authentication timeout The authentication timeout was accidentally overriden by the request timeout. Fix this and set both timeouts in the same place for clarity. ok op@

run gotd authentication in a separate child process ok op@

fork gotd repo_read/repo_write children on demand ok op, jamsek

gotd: tweak error message if getpwnam fails errno may not be set to something interesting so switch to fatalx, and simplify the error message (knowing the failed function, which is also wrong, doesn't buy much here.) ok jamsek

tweaks to request_bad.sh; no functional change in no specific order: - define the "aaa..." string as variable to avoid long lines (same for the 255 "A") - drop the comment about the "OpenBSD cmp(1) offset extension": it's quite popular actually. - consistently use "cmp foo.expected foo" instead of "cmp foo foo.expected". It makes easier to copy-paste it if we want to diff(1) the files. - diff files when cmp(1) fails if feasible (i.e. when we're not cmp(1) at offsets) - use printf when the string to print contains "\n" - add some missing blank lines between functions
