94fb5815f9 [poincare] Fix replaceReplaceableSymbols for parametered expressions 
Scenario: ans*int(0,x,0,0)->x then cos(x) crashed because replaceReplaceableSymbols
would not care if it was replacing parameters in a parametered
expression

94d71634b6 [poincare/unit_convert] In shallowReduce, fix units testing on the right 
First reduce the right member by replacing the units to make sure there
is a unit, then reduce without replacing to keep "complex units" such as
L, N, ...

227a52940d [poincare] Fix Function::deepReplaceReplaceableSymbols, replace 
replaceable symbols in the child first

This fixes the following bug: when checking whether 'blop(g(0))' is
circularly defined with g(x) = blop(g(0)), g(0) was not checked which
triggers a crash.

93832549f1 [poincare] childNeedsUserParentheses takes childIndex param 
Scenario:
0+exp^0 i->b
0+exp b^0 i->b
Go to VariableBox/expression -> Parentheses were not properly added when
b was replaced

e09e36a57f [poincare] When replacing symbols, if it contains itsef return undef 
Circularly defined functions/symbols are detected more quickly, which
prevents some tree pool exhaustions.
For instance, with f(t) = [[f(t)][f(2t)]]

5900dcae0e [poincare] Clean the use of System parentheses from normal parentheses: 
System parentheses are used when serializing a tree to keep the
structure information in the serialization. For example, we serialize
 2+1
----- to [2+3]/3
  3

User parentheses can be added after parsing or when beautifying a
reduced expression to make a mathematically correct expression or more
conventionnal expression. For example, parsing "1+-2" will give
Addition(One, Opposite(2)) that we will transform into Addition(One,
Parenthesis(Opposite(2))) (1+-2 --> 1+(-2)).
