Eric Leblond f46f895e8d rust/smb: import NT status code for Microsoft doc 
This patch updates the NT status code definition to use the status
definition used on Microsoft documentation website. A first python
script is building JSON object with code definition.

```
import json
from bs4 import BeautifulSoup
import requests

ntstatus = requests.get('https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/596a1078-e883-4972-9bbc-49e60bebca55')

ntstatus_parsed = BeautifulSoup(ntstatus.text, 'html.parser')

ntstatus_parsed = ntstatus_parsed.find('tbody')

ntstatus_dict = {}

for item in ntstatus_parsed.find_all('tr'):
    cell = item.find_all('td')
    if len(cell) == 0:
        continue
    code = cell[0].find_all('p')
    description_ps = cell[1].find_all('p')
    description_list = []
    if len(description_ps):
        for desc in description_ps:
            if not desc.string is None:
                description_list.append(desc.string.replace('\n ', ''))
    else:
        description_list = ['Description not available']
    if not code[0].string.lower() in ntstatus_dict:
        ntstatus_dict[code[0].string.lower()] = {"text": code[1].string, "desc": ' '.join(description_list)}

print(json.dumps(ntstatus_dict))
```

The second one is generating the code that is ready to be inserted into the
source file:

```
import json

ntstatus_file = open('ntstatus.json', 'r')

ntstatus = json.loads(ntstatus_file.read())

declaration_format = 'pub const SMB_NT%s:%su32 = %s;\n'
resolution_format = '        SMB_NT%s%s=> "%s",\n'

declaration = ""
resolution = ""

text_max = len(max([ntstatus[x]['text'] for x in ntstatus.keys()], key=len))

for code in ntstatus.keys():
    text = ntstatus[code]['text']
    text_spaces = ' ' * (4 + text_max - len(text))
    declaration += declaration_format % (text, text_spaces, code)
    resolution += resolution_format % (text, text_spaces, text)

print(declaration)
print('\n')
print('''
pub fn smb_ntstatus_string(c: u32) -> String {
    match c {
''')
print(resolution)
print('''
        _ => { return (c).to_string(); },
    }.to_string()
}
''')
```

Juliana Fajardini bbd968c738 exceptions: add reject support to exception policy 
This enables the usage of 'reject' as an exception policy. As for both
IPS and IDS modes the intended result of sending a reject packet is to
reject the related flow, this will effectively mean setting the reject
action to the packet that triggered the exception condition, and then
dropping the associated flow.
