Bence Szépkúti b7246ad938 Add copyright dates to all scripts
To find any files with a missing copyright declaration, use the following script:

# ========================
#!/bin/sh

# Find files with copyright declarations, and list their file extensions
exts=$(grep -Ril --exclude-dir .git 'Copyright.*Arm' | sed '
  s/.*\./-name "*./
  s/$/"/
' | sort -u | sed -n '
  :l
    N
    $!bl
  s/\n/ -o /gp
')

# Find files with file extensions that ususally include copyright extensions,
# but don't include a copyright declaration themselves.
eval "find -path './.git' -prune -o\
  ! -path './tests/data_files/format_pkcs12.fmt'\
  ! -path './programs/psa/psa_constant_names_generated.c'\
  '(' $exts ')' -print" | xargs grep -Li 'Copyright.*Arm'
