fcf5f6cb72 encoding/prototext: allow whitespace and comments between minus sign and number in negative numeric literal 
The text format specification[1] indicates that whitespace and comments
may appear after a minus sign and before the subsequent numeric component
in negative number literals. But the Go implementation does not allow
this.

This brings the Go implementation info conformance with this aspect.

Fixes golang/protobuf#1526

b0a944684d all: reformat with go1.19 gofmt 
Apply go1.19 gofmt to non-generated files.

Generated .pb.go files are created by generate.bash using Go 1.18,
so leave them unchanged for now.

9b3d97c473 encoding/prototext: rewrite of internal/encoding/text 
* Fixes golang/protobuf#842. Unmarshal can now parse singular or
  repeated message fields without the field separator.
* Fixes golang/protobuf#1011. Handles negative 0 properly.
* For unknown fields with fixed 32-bit and 64-bit wire types, output is
  now in hex format with 0x prefix similar to C++ lib output. Previous
  Go implementation simply outputs these as decimal numbers %d.
* All parsing errors, except for unexpected EOF should now contain line
  and column number info.
* Fixed following conformance-related features:
  * Parse nan,inf,-inf,infinity,-infinity as case-insensitive.
  * Interpret float32 overflows as inf or -inf.
  * Parse large int-like number as proto float.
* Discard unknown map field if DiscardUnknown=true.
* Allow whitespaces/comments in Any type URL and extension field names per spec.
* Improves performance and memory usage. It is now as fast and efficient as
  protojson, if not better on most benchmarks.
