Replace instances of wmem_alloc with wmem_new

This commit replaces instances of
  (myobj *)wmem_alloc(wmem_X_scope(), sizeof(myobj))
and replaces them with:
  wmem_new(wmem_X_scope(), myobj)
to improve the readability of Wireshark's code.

Replacements were made with the following Python script:

import os
import re
import sys

pattern = r'\(([^\s\n]+) ?\*\) ?wmem_alloc(0?)\((wmem_[a-z]+_scope\(\)), sizeof\(\1\)\)'
replacewith = r'wmem_new\2(\3, \1)'

startdir = sys.argv[1]

for root, dirs, files in os.walk(startdir):
    for fname in files:
        fpath = os.path.join(root, fname)
        if not fpath.endswith('.c'):
            continue
        with open(fpath, 'r') as fh:
            fdata = fh.read()
        output = re.sub(pattern, replacewith, fdata)
        if fdata != output:
            print(fpath)
            with open(fpath, 'w') as fh:
                fh.write(output)
