* Update the icu4c package

This PR makes several changes to the icu4c package

1. add updated version to 65.1
2. modify the default url as project has moved to github
3. set UTF-8 locale to support building from source files in UTF-8
format

Note that the older versions are not available on github so explicit urls
were used. This PR will close #14399.

* Consolidate the urls

Consolidate the URLs in the `version` directives by using an if test in
`url_for_version`.

* Put version and sha256 on same line

* Put top level url back

* Update and fix bcftools package

This PR updates bcftools to 1.10.2 and is dependent on PR #14504.

This PR also fixes builds of other versions. Versions 1.2-1.4 did not
use autotools so when the packaeg was converted to use autotools with
version 1.6 those older versions could no longer build. Also, those
versions needed to be patched to use an external htsllib. The method of
finding the external htslib is also different for those older versions.

In addition, this PR adds two variants to bcftools:

- libgsl
- perl-filters

Finally, dependencies for perl and python are added, and an unused
dependency for libzip was removed.

* Do not use '@' in variant description

The '@' character in a variant description will cause a problem with
`spack info`.

```
==> Error: Incomplete color format: '@' in
expressions, for @1.8:
```

* Fix error with python2 processing this package

* trnascan-se: add and configure infernal dep

* trnascan-se: use patch() for infernal config

* Update htslib and add libcurl variant

This PR updates htslib to version 1.10.2 and adds a libcurl variant. The
libcurl variant defaults to True because, while it is optional, it is
highly recommended by the project developers.

Other things done:

- be consistent with quotes

* Change version in variant description

Apparently, `spack info` does not like the `@` character in a variant
description.

```
==> Error: Incomplete color format: '@' in
@1.3:.
```

The pathadd function was using setopt to configure zsh for word
splitting, which leaks out of the function and breaks default
functionality in a number of external zsh plugins and packages.  This
switches to emulate -L, just as the spack function uses, to keep the
setting local to the function.
