735709bee6 Add tvb_bcd_dig_to_ep_str() 
/*
 * Given a tvbuff, an offset into the tvbuff, and a length that starts
 * at that offset (which may be -1 for "all the way to the end of the
 * tvbuff"), fetch BCD encoded digits from a tvbuff starting from either 
 * the low or high half byte, formating the digits according to an input digit set, 
 * if NUll a default digit set of 0-9 returning "?" for overdecadic digits will be used.
 * A pointer to the EP allocated string will be returned.
 * Note a tvbuff content of 0xf is considered a 'filler' and will end the conversion.
 */

4f5ccc00f8 Introduce new function called tvb_get_ephemeral_unicode_stringz(), which 
is a unicode (UTF-16) version of tvb_get_ephemeral_stringz().  It scans
a tvbuff for a UTF-16 string and converts it to UTF-8 upon return.

1b444c55fd Refer to the endianness arguments as "encoding" rather than 
"representation" - we already use "representation" to refer to the text
representation of fields.

Change some routines with an endianness argument to make it a
representation argument instead;

} else if (bufsiz > TVB_Z_MAX_BUFSIZ) {

This should probably have been 'bufsiz = TVB_Z_MAX_BUFSIZ;'

b97cfa22fd offset_from_real_beginning() is only called with 0 as second argument, so remove the argument completely. It seems that the second argument only acts as an accumulator allowing offset_from_real_beginning() to call itself recursively. To be consistent offset_from_real_beginning() is renamed to tvb_offset_from_real_beginning().

fe6f8b92c7 Add a new function, tvb_new_subset_remaining(), which is a sligtly optimized version of tvb_new_subset(). The latter can be mapped to the former by tvb_new_subset(tvb, offset, -1 /* backing_length */, -1 /* reported_length */). We can disable some bounds checking because 'backing_length' and 'reported_length' are hardcoded to -1. 
The current implementation of tvb_new_subset_remaining() only has the THROW_ON(reported_length < 1) check removed when compared to tvb_new_subset(). So there's room for improvement in this function. We should be able to disable some more (redundant) bounds checking.

01abc372e6 Remove a non thread-safe usage (useful when/if we ever support threading) of a static tvbuff in tvb_new_real_data(). The current version uses a static 'last_tvb' to keep track of the last allocated tvbuff. This is needed because some of the function we call can throw an exception. This patch improves this strategy by throwing an exception (if needed) before we try to allocate the tvbuff. This way we avoid a memleak _and_ we don't have to track the 'last_tvb' tvbuff.

1f96f14083 Don't support a length of -1 meaning "to the end of the tvbuff" in 
tvb_memcpy(); I changed the one tvb_memcpy() call that was explicitly
depending on that not to do so.  This is a small step towards getting
rid of the "-1 means to end of tvbuff" convention, support for which
requires us to do a bunch of extra checks where, for example, a protocol
has a 32-bit unsigned length field; it also gets rid of a warning about
comparing an unsigned value with a signed value.
