e080cc31f2 pylint: Set a minimum duplicate match to 10 lines.
This patch adjusts pylint to disregard duplicate matches
for up to 10 lines.

The number is chosen to permit overriding with up to
3 identical lines for `def arguments(self)` and
`def result(self)` while two more lines for `arity`
and `input_style` in the bignum test suite.

9a3771e1b3 Don't touch the style of generated files
Ideally the result of the generator would conform to the code style, but
this would be difficult, especially with respect to the placement of line
breaks in long logical lines. So, to avoid surprises when checking the style
of generated files (which happens in releases and in long-time support
branches), systematically skip generated files.

f91090e4a3 Fix an incorrect regex in check_names.py
Allow check_names.py to detect declarations of the form:

enum some_enum_name {

This pattern has only just appeared due to code style correction, which
explains why the issue was not previously noticed.

98d3a67a5c Simplify the coverage statistics summary
The script was parsing the output from `make lcov` to extract numbers and
calculate percentages. But everything including the percentages is already
present in the output of `make lcov`, just with a slightly different
presentation. So replace all this by a simple extraction of the relevant
lines from the output of `make lcov`.

This is more robust than the previous code, which relied on `tail -n4` to
extract relevant lines, which broke when `make lcov` started to emit one
extra line at the end.

acdefdd51a Unify RNG initialization that must be unified
mpi_core_random_basic and mpi_random_values must generate the same random
sequences in order to get the expected test coverage (where we know we'll
hit certain numbers of retries). Facilitate this by defining the RNG seed
only once.

Fix the seed to explicitly list all 16 words of the key. This isn't strictly
required (missing initializer fields get the value zero), but it's clearer.
