Subject: [PATCH] Drop snap package (#2439) (#2583)

The Clash snap package has not been a recommended way to use Clash for
quite some time, and it is a hassle to support.

In order to build a snap package, we build .deb packages for Clash with
Ubuntu 20.04 LTS. But the interaction between the Debian build system
and GHC is problematic, requiring significant effort to support and to
upgrade to a more recent Ubuntu release.

Additionally, snap packages have their own issues on distributions other
than Ubuntu. Given that we no longer recommend people use our snap
package and given the effort required to keep supporting it, we have
decided to drop the snap package.

(cherry picked from commit 070a6d05d8a3698adfe55c6564bd6ef04d6d529b)

-description: |
-  Clash is a functional hardware description language that borrows both its
-  syntax and semantics from the functional programming language Haskell. The
-  Clash compiler transforms these high-level descriptions to low-level
-  synthesizable VHDL, Verilog, or SystemVerilog.

+REMOVED: Dropped the snap package
+
+The Clash snap package has not been a recommended way to use Clash for quite
+some time, and it is a hassle to support.
+
+In order to build a snap package, we build .deb packages for Clash with Ubuntu
+20.04 LTS. But the interaction between the Debian build system and GHC is
+problematic, requiring significant effort to support and to upgrade to a more
+recent Ubuntu release.
+
+Additionally, snap packages have their own issues on distributions other than
+Ubuntu. Given that we no longer recommend people use our snap package and
+given the effort required to keep supporting them, we have decided to drop the
+snap package.
