Changed JSON decoding error message to be more clear.

"No such field:" is more clear than "Unknown field:",
because "unknown field" is a term of art within protocol
buffers that implies that we are preserving the field.
Also "No such field:" matches the pre-existing Ruby
error message.

ee49a8d7df
Added an accessor to get the symtab from a filedef.
...
This matches an API already present in proto2
(const DescriptorPool* FileDescriptor::pool()).
However there is a slightly subtle implication here.
In proto2, the relationship between Descriptor and
MessageFactory is 1:many. You can create as many
DynamicMessageFactory instances as you want, and
each one will have its own independent DynamicMessage
prototype and computed layout for the same underlying
Descriptor. In practice the layouts will all be the same,
but one thing that could be distinct is that each can
have its own extension pool, which is a DescriptorPool
that will be searched for extensions when parsing.
In contrast, upb does not have a separate "message
factory" abstraction. That means that each upb_msgdef
has a single distinct layout, in other words a 1:1
correspondence between descriptor and layout. This means
that there is no way to create multiple message types
for the same descriptor that have distinct extension
pools. If you want a different set of extensions, you
must create a separate upb_symtab with a distinct set
of descriptors.
This change further entrenches that upb_filedef:upb_symtab
is a 1:1 relationship. A single upb_filedef cannot be a
member of multiple symbol tables. In practice this was
already true (there is no way to add a single filedef to
multiple symbol tables) but this change codifies this
1:1 relationship.

Added map sorting to binary and text encoders.
...
For the binary encoder, sorting is off by default.
For the text encoder, sorting is on by default.
Both defaults can be explicitly overridden.
This grows code size a bit. I think we could potentially
shave this (and other map-related code size) by having
the generated code inject a function pointer to the map-related
parsing/serialization code if maps are present.
