Daniel R. Carvalho 5c8983fc18 misc: Fix remaining opening braces 
These were not caught by the previous patches because
the grep used ignored:
- anonymous structures
  (e.g., "struct {")
- opening braces without leading spaces
  (e.g., "struct Name{"),
- weird chars in auto-generation files
  (e.g., "struct $name {").
- extra characters after the opening brace.
  (e.g., "struct Name { // Comment")
- typedefs (note that this is not caught by the verifier)
  (e.g., "typedef struct Name {")

Most of this has been fixed be grepping structures
with the following regex:
  grep -nrE --exclude-dir=systemc \
    "^ *(typedef)* *(struct|class|enum|union) [^{]*{$" src/

The following makes sure that "struct{" is captured:
  grep -nrE --exclude-dir=systemc \
    "^ *(struct|class|enum|union){" src/

To find cases that contain a comment after the
opening brace:
  grep -nrE --exclude-dir=systemc \
    "^ *(struct|class|enum|union)[^{]*{\s*//" src/
