It turns out that the notes section for corefiles (or really any elf
file with multiple notes) is set up in such a way for LLVM formatted
output that the JSON equivalent only has the last note since the notes
are held in a dictionary with every key being Note. This pr alters the
layout for the notes to a list of dictionaries to sidestep this issue
for JSON output. Prior to this pr a note section in the output looked
like (for LLVM output):
```
Notes [
NoteSection {
Name: <?>
Offset: 0x2148
Size: 0x1F864
Note {
Owner: CORE
Data size: 0x150
Type: NT_PRSTATUS (prstatus structure)
Description data (
0000: 06000000 00000000 00000000 06000000 |................|
...
)
}
Note {
Owner: CORE
Data size: 0x88
Type: NT_PRPSINFO (prpsinfo structure)
Description data (
0000: 02440000 00000000 04054040 00000000 |.D........@@....|
....
```
But is now:
```
NoteSections [
NoteSection {
Name: <?>
Offset: 0x2148
Size: 0x1F864
Notes [
{
Owner: CORE
Data size: 0x150
Type: NT_PRSTATUS (prstatus structure)
Description data (
0000: 06000000 00000000 00000000 06000000 |................|
...
)
}
{
Owner: CORE
Data size: 0x88
Type: NT_PRPSINFO (prpsinfo structure)
Description data (
0000: 02440000 00000000 04054040 00000000 |.D........@@....|
...
