http: drop custom http client logic

Eight and a half years ago, as my starter bug on code.google.com, I
investigated a mysterious "broken pipe" error from seemingly random
clients[0]. That investigation revealed a tragic story: the Python
standard library's httplib was (and remains) barely functional. During
large POSTs, if a server responds early with an error (even a
permission denied error!) the client only notices that the server
closed the connection and everything breaks. Such server behavior is
implicitly legal under RFC 2616 (the latest HTTP RFC as of when I was
last working on this), and my understanding is that later RFCs have
made it explicitly legal to respond early with any status code outside
the 2xx range.

I embarked, probably foolishly, on a journey to write a new http
library with better overall behavior. The http library appears to work
well in most cases, but it can get confused in the presence of
proxies, and it depends on select(2) which limits its utility if a lot
of file descriptors are open. I haven't touched the http library in
almost two years, and in the interim the Python community has
discovered a better way[1] of writing network code. In theory some day
urllib3 will have its own home-grown http library built on h11[2], or
we could do that. Either way, it's time to declare our current
confusingly-named "http2" client logic and move on. I do hope to
revisit this some day: it's still garbage that we can't even respond
with a 401 or 403 without reading the entire POST body from the
client, but the goalposts on writing a new http client library have
moved substantially. We're almost certainly better off just switching
to requests and eventually picking up their http fixes than trying to
live with something that realistically only we'll ever use. Another
approach would be to write an adapter so that Mercurial can use pycurl
if it's installed. Neither of those approaches seem like they should
be investigated prior to a release of Mercurial that works on Python
3: that's where the mindshare is going to be for any improvements to
the state of the http client art.

Issue3841: check annotation of the file of which filelog includes
merging between the revision and its ancestor

to reproduce the situation with recent Mercurial, this script uses (1)
"hg debugsetparents" to merge without ancestor check by "hg merge",
and (2) the extension to allow filelog merging between the revision
and its ancestor by overriding "repo._filecommit".

Test empty annotate output

  $ printf '\0' > binary
  $ touch empty
  $ hg ci -qAm 'add binary and empty files'

  $ hg annotate binary empty
  binary: binary file

  $ hg annotate -Tjson binary empty
  [
   {
    "abspath": "binary",
    "path": "binary"
   },
   {
    "abspath": "empty",
    "lines": [],
    "path": "empty"
   }
  ]

Test annotate with whitespace options

  $ cd ..
  $ hg init repo-ws
  $ cd repo-ws
  $ cat > a <<EOF
  > aa
  > 
  > b b
  > EOF
  $ hg ci -Am "adda"
  adding a
  $ sed 's/EOL$//g' > a <<EOF
  > a  a
  > 
  >  EOL
  > b  b
  > EOF
  $ hg ci -m "changea"

Annotate with no option

  $ hg annotate a
  1: a  a
  0: 
  1:  
  1: b  b

Annotate with --ignore-space-change

  $ hg annotate --ignore-space-change a
  1: a  a
  1: 
  0:  
  0: b  b

Annotate with --ignore-all-space

  $ hg annotate --ignore-all-space a
  0: a  a
  0: 
  1:  
  0: b  b

Annotate with --ignore-blank-lines (similar to no options case)

  $ hg annotate --ignore-blank-lines a
  1: a  a
  0: 
  1:  
  1: b  b

  $ cd ..

Annotate with linkrev pointing to another branch
------------------------------------------------

create history with a filerev whose linkrev points to another branch

  $ hg init branchedlinkrev
  $ cd branchedlinkrev
  $ echo A > a
  $ hg commit -Am 'contentA'
  adding a
  $ echo B >> a
  $ hg commit -m 'contentB'
  $ hg up --rev 'desc(contentA)'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo unrelated > unrelated
  $ hg commit -Am 'unrelated'
  adding unrelated
  created new head
  $ hg graft -r 'desc(contentB)'
  grafting 1:fd27c222e3e6 "contentB"
  $ echo C >> a
  $ hg commit -m 'contentC'
  $ echo W >> a
  $ hg log -G

Annotate should list ancestor of starting revision only

  $ hg annotate a
  0: A
  3: B
  4: C

  $ hg annotate a -r 'wdir()'
  0 : A
  3 : B
  4 : C
  4+: W

Even when the starting revision is the linkrev-shadowed one:

  $ hg annotate a -r 3
  0: A
  3: B

  $ cd ..
