Change company name to "rev.ng Labs Srl" in all license headers
to reflect changed company name and legal status
Add missing license headers to files that didn't have one
Before this commit, each dla::Step handled the printing of its own .dot
files for debug.
This commit moves the logic for dumping the .dot files into the main
loop of dla::StepManager, guarding it with a single Logger.
Before this commit, the dla::Step RemoveInvalidStrideEdges was not
taking into account that dropping edges could change the size of the
node where the edges originated from.
This commit fixes the problem, a) recomputing the size automatically
when needed, and b) adding proper dependencies in the dla middleend
pipeline, so that these changes are properly propagated updwards and
don't break any pre-conditions of following dla::Steps.
