Subject: services: web: Add support for configuring the nginx server names
hash.
The nginx service can fail to start if the server names hash bucket size is
too small, which can happen on some systems, and when using QEMU, depending on
the CPU.
* gnu/services/web.scm (<nginx-configuration>): Add
server-names-hash-bucket-size and server-names-hash-bucket-max-size.
(default-nginx-config): Add support for the new hash bucket size parameters.
(nginx-service, nginx-activation): Pass the new hash bucket size parameters
through to the default-nginx-config procedure.
* doc/guix.texi (Web Services): Document the new hash bucket size parameters.
