http-client: 'http-multiple-get' is tail-recursive again.
Fixes <https://bugs.gnu.org/47283>.
Commit 205833b72c5517915a47a50dbe28e7024dc74e57 made 'http-multiple-get'
non-tail-recursive. Each recursive call would install an exception
handler. As the number of iterations grows beyond 1,000, quadratic
complexity of 'raise-exception' would show and we'd spend most of our
time there.
* guix/http-client.scm (false-if-networking-error): New macro.
(http-multiple-get): Use it around 'write-request' and 'put-bytevector'
calls, and around 'read-response' call, in lieu of the inline 'catch'
forms.
