e30ee90478 Revert "Handle CRLF and Unicode line endings in read-line"
This reverts commit 0f983e3db0.

After discussing with Mike we are going to punt the read-line changes
for now.  Open the port in O_TEXT mode if you want to chomp the CR in
CFLF sequences.

c9b83a27c7 web: Adjust (gnutls) loading to new module autoload semantics.
Prior to commit cb14fd2143 (Guile 2.9.7),
autoloading a module would give you access to all its bindings.  In
future versions, autoloading a module gives access only to the listed
bindings, as per #:select (see <https://bugs.gnu.org/38895>).

This commit adjusts autoloads to the new semantics, fixing a regression
introduced in cb14fd2143.

* module/web/client.scm <top level>: Remove 'module-autoload!' call.
(gnutls-module, ensure-gnutls): Remove.
(load-gnutls): New procedure.
(tls-wrap): Call it instead of 'ensure-gnutls'.  Replace reference to
GNUTLS-MODULE by a call to 'resolve-interface'.

0c102b56e9 Fix reading of HTTPS responses that are smaller than port buffer
* module/web/client.scm (tls-wrap): Use get-bytevector-some instead of
  get-bytevector-n, to prevent Guile from attempting to read more bytes
  than are available.  Normally trying to read data on a shut-down
  socket is fine, but but gnutls issues an error if you attempt to read
  data from a shut-down socket, and that appears to be a security
  property.  Fixes HTTPS requests whose responses are smaller than the
