[tofu] disable libtls name verification

fmt + avoid possible errors

typo

yield_w after a failed connect

first draft of asynchronous dns resolution Use asr on OpenBSD to do DNS query lookups asynchronously. At the moment it seems a bit hard to provide the whole asr + asr_event stuff in the compat layer, so hide those bits behind an #ifdef; not the prettiest solution, but a working one. Future works may either: - provide a stub implementation for the asr stuff - bundle the libasr from OpenSMTD-portable

retire telescope_strnchr in favor of memmem

don't need to save the \n position

introduce close_with_errf (refactoring errors code path)

don't crash on handshake failures ty gemini://discovery.geminiprotocol.com =)

de-duplication: factorize dispatch_imsg

fix various warnings, no functional changes now that we have a bounch of -Wxxx flags during compilation, let's fix everything.

added fs process it's the only one that has file system access. For now it serves about:new (from memory) and about:bookmarks (from ~/.telescope/bookmarks.gmi if found)

don't printf

set the off to zero after flushing the buffer this was the cause we had duplicated "chunks" in the pages: if we enter copy_body with req->off != 0 but then tls_read returns WANT_POLLIN/POLLOUT, the next time we flush the same chunk again.
