Bugfix for pmpi usage

See merge request !25

The PMPI code has been broken for a while, so fix the various issues in it.
More importantly, recent testing uncovered issues with symbols exported by our library being in conflict with the ones available in applications, when compiled against different build systems.

We managed to fix this by only exporting the PMPI symbols.

Resolve "Better ratelimiting"

Closes #6

See merge request !23

- phase context reporting is not managed by NRM_DAMPER anymore,
the reporting is done directly with nrm_send_phase_context.
- deleted the arguments aggregation and totalTime for the nrm_send_phase_context
function since both can be incremented/computed in it.
- deletion of the skipping of some phases.
- deletion of all functions not interacting with nrm
- no more transmit function
- modified the utility function to calculate a time difference and used it in
dowmstream_api.
- modified the MPI_Init to take the name of the application as uuid for
nrm
- propagated the modifications in the Fortran interface.

Header file separation

See merge request !22

Moves the message format out of the main header file. Also
fixes the format to comply with the new nrm schemas, enables
-Werror and cleans the gitlab-ci file.

[fix] Fixed msg formats for new msg layer

See merge request !10

Made necessary changes in the downstream_api and mpi_api for the
power policy to work correctly with the new downstream messaging
layer in the NRM

[feature] allow ratelimit change with envvar

See merge request !21

Transform the internal ratelimit threshold into a static variable that
can be modified at init by an environment variable. This will allow
users to tune the ratelimit based on what they know of the progress
reports.

Related to #6.

[ci] add .repoquality

See merge request !20

[fix] Handle dropped progress messages

See merge request !19

[doc] Licensing

See merge request !16

See #5.

Non-blocking progress sends

See merge request !18

Ensure that if the zmq_send would block on a progress report, we instead
just ratelimit the message.

[ci] fix typo: .gitlab-ci.yml

See merge request !17

Updating the CI tests.

See merge request !15

This commit simplifies greatly the CI logic and improves its
maintability. argopkgs/master becomes the single maintained
authoritative soure of content for CI and packaging.

[Fix] rate limiting never let any message through

See merge request !14

Add Fortran interface for libnrm

See merge request !13

Use the "base" and "basic" CI test references.

See merge request !12

This should be the last CI-reference-switching-related commit in the
history of this repository, as in the future the pointed test should be
the one to move.

[fix] Added execute file permissions to autogen.sh

See merge request !9

[feature] adding application uuid to progress messages.

See merge request !8

[fix] fixing extra quotes in the message format.

See merge request !7

removing extra quotes, adding 'api' field, 'event' -> 'type'

[ci] Offloading CI versioning to argotest.

See merge request !6

This commits simplifies the CI setup for this repository, offloading all
complexity to the "argotest" repository.

The ci setup was also changed to better isolate library building
from integration tests.
