This makes it easier to understand the code, avoids conflicts
and ugly and unnecessary casts.
The field display enum has evolved over time from integer types
to a type generic parameter.
Replace:
g_snprintf() -> snprintf()
g_vsnprintf() -> vsnprintf()
g_strdup_printf() -> ws_strdup_printf()
g_strdup_vprintf() -> ws_strdup_vprintf()
This is more portable, user-friendly and faster on platforms
where GLib does not like the native I/O.
Adjust the format string to use macros from intypes.h.
These display bases work to replace unprintable characters so the
name is a misnomer. In addition they are the same option and this
display behaviour is not something that is configurable.
This does not affect encodings because all our internal text strings
need to be valid UTF-8 and the source encoding is specified using
ENC_*.
Remove the assertion for valid UTF-8 in proto.c because
tvb_get_*_string() must return a valid UTF-8 string, always, and we
don't need to assert that, it is expensive.
It's not a valid field type, it's only a hack to support regular
expression matching in packet-matching expressions.
Instead, in the packet-matching code, have a separate syntax tree type
for Perl-compatible regular expressions, and a separate instruction to
load one into a register, and have the "matching" operator for field
types take a GRegex * as the second argument.
Adds a pre-commit hook for detecting and replacing
occurrences of `g_malloc()` and `wmem_alloc()` with
`g_new()` and `wmem_new()`, to improve the
readability of Wireshark's code, and
occurrences of
`g_malloc(sizeof(struct myobj) * foo)`
with
`g_new(struct myobj, foo)`
to prevent integer overflows
Also fixes all existing occurrences across
the codebase.
FT_STRINGZPAD is for null-*padded* strings, where the field is in an
area of specified length, and, if the string is shorter than that
length, all bytes past the end of the string are NULs.
FT_STRINGZTRUNC is for null-*truncated* strings, where the field is in
an area of specified length and, if the string is shorter than that
length, there's a null character (which might be more than one byte, for
UCS-2, UTF-16, or UTF-32), and anything after that is not guaranteed to
have any particular value.
Use IS_FT_STRING() in some places rather than enumerating all the string
types, so that those places get automatically changed if the set of
string types changes.
If a ProtoField object was created, but not linked to a Proto, then the
strings field and all elements (depending on type) would leak.
This is a follow-up to g79fef2ae and fixes the real issue in g44870fb1.

A range string is passed as a table of tables, eg:
range_string = {
{ 0, 24, "Some string for values 0 to 24" },
{ 25, 25, "The string for value 25" },
{ 26, 255, "The string for the remainder" }

Included is a minimal Lua test for range strings and value strings
(which did not have one previously.) It will take more time than I
currently have to figure out how to do a more exhaustive test.
Also fixed some grammar issues in error messages along the way.
