maybeDecompress: bail on all errors at the beginning of the stream with zlib < 0.6

Fix #2704

Code branch with zlib <0.6 cannot recognise the uncompressed input.

Add missing test modules

Use the version macros when building Setup.hs

The design called for allowing deps to be specified, and for the
Setup.hs to be able to use the same version macros as in other code.
This patch completes that second part.

Fix: 7.4.2 compat.

PVP compliance: upper version bound.

Revert noise and relax zlib min version back to 0.5.3 (part 1/2).

Revert noise and relax zlib min version back to 0.5.3 (part 2/2).

Test cases for maybeDecompress.

Use edsko's implementation of maybeDecompress; add test case.

Fixup.

maybeDecompress: test suite work-around.

Cleanup.

Relax zlib upper bound.

maybeDecompress: add mysteriously failing test cases.

7.4 compat for test cases.

Warn if GHC{,JS}_PACKAGE_PATH points to non-directory

Merge https support

e.g. cabal install https://example.com/foo-1.0.tar.gz

The initial patch would always try to use HTTPS, even when the repo
specified to use HTTP. This works for the central community hackage
but obviously does not work in general.

The new logic is that we always follow what is specified for the
remote repo in the config, except for built-in known repos (currently
just the central community hackage) where we mark them as also
supporting https. For upload when uploading to such a marked repo
then we will try https and will complain if the plain-http impl was
selected automatically (but it's ok if selected manually).

This patch also changes things so that for http urls on download, we
stick to the builtin http impl by default, and only use the external
ones if https support is required (i.e. because the repo was
configured to use an https url)

Move utils into other Util modules.
Reformat all code to 80 cols.
Reorder code and add more comments.
Use long form style program args, e.g. --silent rather than -s
Finish implementation of form upload with wget
Fix reporting of server error messages for upload (curl & builtin)
Implement collecting of ETags for curl and wget.
Fix wget for case of 304 not modified response (wget uses exit code 8).
Rework transport configuration phase.

Supports both uploading and downloading.
Basic built-in HTTP is still supported.

Get 'builddir' from cabal.config or CABAL_BUILDDIR

This will be useful for adding crypto credentials without people having
to update their config files.

Also useful point to add any other special casing for known repos.

Will need a later check to validate the repo info, e.g. that it's a
supported url scheme and is an absolute URI.

Add test dependencies to stack.yaml

Support new section syntax for remote-repo.

Fixes #2484. The 'builddir' option may now be specified in cabal.config
as well. It will also be read from the CABAL_BUILDDIR environment
variable, if set. The order of precedence (highest to lowest) is:
1. --builddir command line option
2. CABAL_BUILDDIR environment variable
3. cabal.config setting

HACKING.md: Add quotation to sed command

The command line given to get the sandbox package database path is missing quotation which may make it fail in some shells (given certain globbing options). This adds single quotation marks to avoid such potential issues.

Add a stack.yaml file

I needed this when building cabal.exe for MinGHC (see:
https://github.com/fpco/minghc/issues/69). I thought others might find
this useful, especially for the use case of bootstrapping cabal
development.

I went the direction of no curation and explicit packages in the
extra-deps, as I thought that would make more sense for a project low on
the dependency chain, but this could certainly be tweaked to use LTS
Haskell or Stackage Nightly instead.
