Prevent out-of-bounds read when deserializing 
We first serialize the total number of tags, then serialize each individual
tag. If we don't have enough space to serialize a particular tag we stop
serializing any remaining tags.

However, this causes an out-of-bounds read when deserializing because there are
less tags than expected. Just bail when there are too many tags to serialize.

Avoid integer cast issues when deserializing tags 
`buffer` contains signed chars, so if a tag length is greater than 128 then it
is treated as a negative value when deserializing. The negative signed char is
then implicitly cast to a large unsigned integer. Explicitly cast the values to
signed chars

Avoid integer truncation when serializing tag lengths 
A tag longer than 255 characters will be incorrectly serialized.

Max Brunsfeld 3ba95dbf3e Represent tag name map as a std::map 
This doesn't seem to affect performance, and unordered_map requires
C++11.
