publish: Defer narinfo string creation to the http-write.
The "narinfo-string" procedure is expensive in term of IO operations and can
take a while under IO pressure, such a GC collecting. Defer its call to a new
thread created in the http-write procedure.

Fixes: <https://issues.guix.gnu.org/48468>
Partially fixes: <https://issues.guix.gnu.org/49089>

* guix/scripts/publish.scm (render-narinfo): Defer the narinfo string creation
to the http-write procedure.
(compression->sexp, sexp->compression): New procedures.
("X-Nar-Compression"): Use them.
("X-Narinfo-Compressions"): New custom header.
(strip-headers): Add the x-nar-path header.
(http-write): Add narinfo on-the-fly creation support. It happens in a
separated thread to prevent blocking the main thread.

import: go: Recognize major version suffixes.

* guix/import/go.scm (go-module->guix-package): When determining the
unpack path, compare 'root-module-path' to 'module-path-sans-suffix'
instead of 'module-path'.

import: pypi: Honor the 'upstream-name' package property.
Previously, when a PyPI package had a “-” followed by one or more digits in
its name, e.g., “AV-98”, the importer would interpret “98” as the version of
the package and thus mistake the “AV-98” package for the “av” package on PyPI.

  $ ./pre-inst-env guix refresh av-98
  following redirection to `https://pypi.org/pypi/av/json'...
  /home/yoctocell/src/guix/gnu/packages/web-browsers.scm:914:13: av-98 would be upgraded from 1.0.1 to 8.0.3

Setting the ‘upstream-name’ property to “AV-98” would solve the problem.

  $ ./pre-inst-env guix refresh av-98
  /home/yoctocell/src/guix/gnu/packages/web-browsers.scm:914:13: 1.0.1 is already the latest version of av-98

swh: Adjust to new vault API.
Previously the path to query the vault or request cooking of a directory
was /api/1/vault/directory/ID.  It is now deprecated in favor if
/api/1/vault/flat/SWHID.  This commit adjusts code accordingly and also
prepares for 'git-bare' support.

* guix/swh.scm (vault-url): New procedure.
(query-vault, request-cooking): Make 'kind' optional, and add #:archive-type.
Use 'vault-url'.
(vault-fetch): Make 'kind' optional and add #:archive-type.  Adjust
'query-vault' and 'request-cooking' calls accordingly.

This makes bytevector->base16-string two times faster.

* guix/base16.scm (bytevector->base16-string): Use utf8->string
  and iteration instead of string-concatenate and named let.
