* deprecate Data.Nat.Order.decideLTE
* Add properties for LTE/GTE that produce the difference.
* remove deprecated function now that it is available in the base library.
* remove two deprecated lines.
* remove module deprecated since v0.4.0
* fix prelude reference to renamed primitive.
* finish removing Data.Num.Implementations
* remove deprecated dirEntry function.
* remove deprecated fastAppend. Update CHANGELOG.
* replace fastAppend in test case
* replace fastAppend uses in compiler.
* remove new properties that weren't actually very new.
* Update version numbers and bootstrap scheme
* Use wall clock time for search timeouts
That was always the intention in any case, rather than the process time.
When bootstrapping, we're building things without packages being
available, so we can't expect to find them when looking for
dependencies. So, we find them another way, with an environment
variable. This flag is to tell Idris not to worry about missing
dependencies in this situation.
We also need to update the bootstrapping code, to deal with the new
version number format and new flag in the ipkg files for the libraries.
I think it's still safe to build from the previous version though - lets
see if CI agrees!
Packages are now installed in a directory with their version number.
On adding a package directory, we now look in a local 'depends'
directory first (to allow packages to be installed locally to another
project) before the global install directory.
Dependencies can have version bounds (details yet to be implemented) and
we pick the package with the highest version number that matches.
This is an alternative to using `fastUnpack` and `fastPack` to work
on lists of characters.
Using this to refactor the lexer and benchmarking the resulting
compiler on building idris2 shows it's 3 to 5s slower than the
current implementation that goes via `List Char`.
This may be backend-dependent so I still push this to contrib,
with the plan of running further benchmarks in the future.
