The argument order differs for the cdeps library vs. the individual
components. Thus, we need a different function to parse the command line
for the library. The new parse_command_line function is a direct copy of
the same function from buildlib.csm_share.

To handle this difference in command-line arguments in the two
situations, I have renamed the old file to buildlib_comps (which is
identical to the old buildlib); the individual data model components now
point to that file, leaving buildlib just being used for the cdeps
shared library.

In a following commit I will remove unnecessary code from each of these
files.

Resolves ESCOMP#104

It turns out that, for the most part, each line of code was just needed
for one of these, not both. So, now that the unnecessary code is removed
from each, there is essentially no duplication between buildlib and
buildlib_comps.

Allow none mapalgo. For single-point runs of CTSM, we need to be able to set `foo:mapalgo=none` , where `foo` is the stream name.  `none` as an option to `cime_config/stream_cdeps.py`

Updates download path for NEON data, the new path is a virtual address so in the future the
actual location of the server can be updated without further changes here.

Revert PR ESCOMP#123

### Description of changes

PR ESCOMP#123 (solar zenith angle correction) led to exact restart failures in some situations: see ESCOMP#144. This PR backs out the changes from ESCOMP#123 .

### Specific notes

Contributors other than yourself, if any:

CDEPS Issues Fixed (include github issue #): Temporarily deals with ESCOMP#144.

Are there dependencies on other component PRs (if so list): no

Are changes expected to change answers (bfb, different to roundoff, more substantial): more substantial. I have verified that this brings answers back to being bfb with those in cdeps0.12.35 (i.e., prior to ESCOMP#123) via a run of the aux_clm test suite.

Any User Interface Changes (namelist or namelist defaults changes): no

Testing performed (e.g. aux_cdeps, CESM prealpha, etc): aux_clm
