This simplifies the logic of recursive-import, intending no
major functional changes. The package import function is no
longer called twice per package. Failed imports now make it
to the package stream as '() instead of #f.

This adds partial support for Cabal properties that use curly
braces instead of the layout rule. See for example
https://hackage.haskell.org/package/cassava/

(lex-layout-property): ... this.
(lex-braced-property, lex-property): New procedures.

When a server publishes several URLs with different compression methods,
'guix substitute' can now choose the best one among the compression
methods that it supports.
* guix/scripts/substitute.scm (<narinfo>)[uri]: Replace with...
[uris]: ... this.
[compression]: Replace with...
[compressions]: ... this.
[file-size]: Replace with...
[file-sizes]: ... this.
[file-hash]: Replace with...
[file-hashes]: ... this.
(narinfo-maker): Adjust accordingly. Ensure 'file-sizes' and
'file-hashes' have the right length.
(assert-valid-signature, valid-narinfo?): Use the first element of
'narinfo-uris' in error messages.
(read-narinfo): Expect "URL", "Compression", "FileSize", and "FileHash"
to occur multiple times.
(display-narinfo-data): Call 'select-uri' to determine the file size.
(%compression-methods): New variable.
(supported-compression?, compresses-better?, select-uri): New
procedures.
(process-substitution): Call 'select-uri' to select the URI and
compression.
* guix/scripts/weather.scm (report-server-coverage): Account for all the
values returned by 'narinfo-file-sizes'.
* tests/substitute.scm ("substitute, narinfo with several URLs"): New
test.
This allows 'guix publish' to compress and advertise multiple
compression methods from which users can choose.
* guix/scripts/publish.scm (actual-compression): Rename to...
(actual-compressions): ... this. Expect REQUESTED to be a list, and
always return a list.
(%default-options): Remove 'compression.
(store-item->recutils): New procedure.
(narinfo-string): Change #:compression to #:compressions (plural).
Adjust accordingly.
(render-narinfo, render-narinfo/cached): Likewise.
(bake-narinfo+nar): Change #:compression to #:compressions.
[compressed-nar-size]: New procedure.
Call 'compress-nar' for each item returned by 'actual-compressions'.
Create a narinfo for each compression.
(effective-compression): New procedure.
(make-request-handler): Change #:compression to #:compressions.
Use 'effective-compression' to determine the applicable compression.
(guix-publish): Adjust handling of '--compression'.
Print a message for each compression that is enabled.
* tests/publish.scm ("/*.narinfo"): Adjust to new narinfo field
ordering.
("/*.narinfo with properly encoded '+' sign"): Likewise.
("/*.narinfo with lzip + gzip"): New test.
("with cache, lzip + gzip"): New test.
* doc/guix.texi (Invoking guix publish): Document it.
* guix/build/guile-build-system.scm (invoke-each)[processes]: New
variable.
[wait-for-one-process]: Check PROCESSES and update it.
[fork-and-run-command]: Update PROCESSES.
Tests fail reliably for me on a system with 2GB of available RAM, in
`issue93.a.hs` and `issue93.n.hs`.
* gnu/packages/haskell.scm (ghc-happy): Skip test "issue93".

Suggested by Pierre Neidhardt <mail@ambrevar.xyz>.
* guix/lzlib.scm (lzread!): Call 'lz-decompress-finish' when
'feed-decoder!' returns EOF. Call 'lz-decompress-finished?' to
determine end of compression.
Update the list of excepted dependencies for current ghc-8.4, based on the
release notes at
https://downloads.haskell.org/~ghc/8.4.3/docs/html/users_guide/8.4.3-notes.html
Particularly, this adds `text` to the list, which is a dependency of `parsec`
which was already on the list before, causing build failures with updated
versions of the `text` package.
* guix/import/hackage.scm (ghc-standard-libraries): Update list.
