Replace instances of wmem_alloc with wmem_new

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

The replacement locations were identified with grep
and replaced with the Python script below.

grep command:
  egrep "wmem_alloc0?\(wmem_file_scope\(\), sizeof\([a-z_]+\)\)" . -R -l

python script:

import re
import sys
import fileinput

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

fname = sys.argv[1]

for line in fileinput.input(fname, inplace=1, mode='rb'):
    output = re.sub(pattern, replacewith, line)
    sys.stdout.write(output)
