After running pytest not everything was cleaned up, it is now.

The stuff that wasn't cleaned up was:
- Some Makefile's
- 020git_fetch/ipcores.old/
- 048err_two_manifest/manifest.py

If a package body exists, then it is included as dependency for its package.

Note:
This implementation does not handle selecting the correct architecture
between multiple architectures.

All testcases pass

If entity and architecture are in separate files, then the
architecture isn't included in dependencies.

Vivado: Compile to --work <library>

See merge request !26

Prior Vivado compiled to work, now it compiles to the library specified in Manifest.py

Develop merge master

Fixes for XCI parsing in Python 3.6

See merge request !23

- Support JSON format XCI files (#119)
- Support XCIX files (#120)

Rework XCI file parsing

See merge request !22

- Support JSON format XCI files (#119)
- Support XCIX files (#120)

Add partial support for VHDL generic packages

See merge request !21

This adds support for generic packages declaration dependency
tracking. It is not complete though, it only works when instantiating
a generic package for using withing the same file.

so hdlmake can satisfy dependencies declared by qips

Following commmit implements to standard makefile argument
"syn_properties" as well additional 3:

- syn_instances -> set_global_instance
- syn_location_assignments-> set_location_assignment
- syn_instance_assignments -> set_instance_assignment

The original foreseen only

- syn_properties -> set_global_assignment

Following brings possibility to specify in manifest in more detail for
example logilock regions.

In order to make the parameters compatible with quartus manifest
properties 'to' and 'region_id' can be now preprended by tilde (~) to
announce that the given value of the command shall be enclosed in
quotes. This is needed as it differs from parameter to
parameter. Example:

following does not need any quotes:

set_global_assignment -name IOBANK_VCCIO 3.3V -section_id 3A

but following does:

set_instance_assignment -name LL_MEMBER_OF "bst_sync:i_bst_sync" -to
"VfcHdApplication:i_VfcHdApplication|bran:i_bran|bst_sync:i_bst_sync"
-section_id "bst_sync:i_bst_sync"

Needed to setup certain global properties, as e.g.

set_global_assignment -name OUTPUT_IO_TIMING_FAR_END_VMEAS "HALF SIGNAL SWING" -rise

lib components are ignored during dependency search

in addition to original CLEAN_TARGETS this commits as well:

- a5_pin_model_dump.txt
- *.sld

to be erased when 'make clean' is issued
