revert my previous two commits because they broke clone over http

make got-fetch-http get_refs() understand when packet lines end Previously it would only exit the loop when reading failed. ok tobhe@

log pkt lines read and written by got-fetch-http, in verbose mode

gotd: don't ignore error in session_dispatch_repo_child ok stsp

got-notify-http: implement basic authentication ok stsp

add comments to the HTTP fetching process which clarify how it works

Remove some dead code

Rewrite got-fetch-http I/O using bufio API. This should help make the code more portable supports almost everything we need out of the box. pledge needs the rpath promise because of libtls. This was technically also the case with the old API but we didn't actually enable pledge thanks to DEBUG_HTTP. The synchronous bufio wrappers should probably move to lib/bufio.c in the future. ok and feedback from op@

for now, remove a workaround for http fetch that was added for unknown reasons ok op@

got-notify-http: add the repository name in the json ok stsp

Unset errno and bio->wantev if error was not TLS_WANT_*. This is commonly called in a loop, if we don't clear them we might keep on looping. ok stsp@

improve got-fetch-http request/response logging in verbose mode

man page updates for HTTP clone/fetch support

Rename got-http helper to got-fetch-http to match naming scheme. We aren't planning to support sending anyway. ok stsp@

Add initial read-only http fetch support using a got-http helper. Currently we only support the smart protocol with a limited feature set. ok stsp@ tobhe@

get rid of unnecessary "dns inet" pledge promises while fetching via git://

drop privileges in all parts of gotd other than the main process ok thomas_adam

remove outdated TOOD item and tweak test accordingly The default deny policy is working as expected according to newly added regression test. Tweak this test to use an implicit read-only rule, rather than an explicit one, as stated in the TODO item.

add test for read-only access on empty repository

portable: README: mention jot's removal Upstream has now moved from jot -> seq.

fix gotd notification test failures due to missing shell quoting The expected output generated by test scripts was wrong on days with a single-digit date. Found by Omar's regress builder. ok op@

regress: use seq instead of jot This is just for -portable since jot is not always available. ok stsp@

cast a time_t to long long for printf for portability

remove trailing whitespaces

got.1: escape Eq since it's a GNU roff macro `.Op Fl Eq' gets rendered as [-] with groff because Eq it's a macro. Escape it to get it rendered correctly. Discussed with bentley. Reported by casaca on the IRC channel, thanks!
