Preparation for the 2.10 release (#972)

* Update CHANGES for 2.10

* Remove profiling flags from Cabal file

They result in `cabal check` warnings and probably don’t need to be
hard-coded.

* Remove commented-out Cryptol server references

The code no longer exists, so we’ll never uncomment these.

Equivalent functionality is now provided by `cryptol-remote-api`.

* Update references to version numbers in README. Closes #719.

+# 2.10.0
+
+## Language changes
+
+* Cryptol now supports primality checking at the type level. The
+  type-level predicate `prime` is true when its parameter passes the
+  Miller-Rabin probabilistic primality test implemented in the GMP
+  library.
+
+* The `Z p` type is now a `Field` when `p` is prime, allowing additional
+  operations on `Z p` values.
+
+* The literals `0` and `1` can now be used at type `Bit`, as
+  alternatives for `False` and `True`, respectively.
+
+## New features
+
+* The interpreter now includes a number of primitive functions that
+  allow faster execution of a number of common cryptographic functions,
+  including the core operations of AES and SHA-2, operations on GF(2)
+  polynomials (the existing `pmod`, `pdiv`, and `pmult` functions), and
+  some operations on prime field elliptic curves. These functions are
+  useful for implementing higher-level algorithms, such as many
+  post-quantum schemes, with more acceptable performance than possible
+  when running a top-to-bottom Cryptol implementation in the
+  interpreter.
+
+  For a full list of the new primitives, see the new Cryptol
+  [`SuiteB`](https://github.com/GaloisInc/cryptol/blob/master/lib/SuiteB.cry)
+  and
+  [`PrimeEC`](https://github.com/GaloisInc/cryptol/blob/master/lib/PrimeEC.cry)
+  modules.
+
+* The REPL now allows lines containing only comments, making it easier
+  to copy and paste examples.
+
+* The interpreter has generally improved performance overall.
+
+* Several error messages are more comprehensible and less verbose.
+
+* Cryptol releases and nightly builds now include an RPC server
+  alongside the REPL. This provides an alternative interface to the same
+  interpreter and proof engine available from the REPL, but is
+  better-suited to programmatic use. Details on the protocol used by the
+  server are available
+  [here](https://github.com/GaloisInc/argo/blob/master/docs/Protocol.rst).
+  A Python client for this protocol is available
+  [here](https://github.com/GaloisInc/argo/tree/master/python).
+
+* Windows builds are now distributed as both `.tar.gz` and `.msi` files.
+
