Thank you, this looks good to me.

I wonder if there's a better way. It's ok if not, this is just
giving me bad memories of the way the disassembly code manages
this stuff.

I don't know of any other way to get the structured MI output without creating and destroying all of these different ui_out_emit_* objects, however, I've tried harder to hide the complexity. I'm not completely convinced that the new way is better - I'd be interested to hear your thoughts.
If you prefer this then there's a later patch in this series that could get the same treatment. I've not done that yet because, like I said, I'm not completely convinced the new code is that much better.

gdb/mi: Add new commands -symbol-info-{functions,variables,types}
Add new MI commands -symbol-info-functions, -symbol-info-variables,
and -symbol-info-types which correspond to the CLI commands 'info
functions', 'info variables', and 'info types' respectively.
gdb/ChangeLog:

Patch Set 3:

Since you were looking for suggestions for how to make the output code less ugly: I think the best way would be to make the result from the symbol search code more structured from the start, not just return a flat list of symbols. That might not be a realistic goal for the short term though.
But what you can do now is iterate on the vector as if it was structured like that:
if there are debug symbols:
prepare the emitter for debug symbols
for each symtab:
prepare the emitter for the symtab
for each symbol:
output the symbol
if there are non-debug symbols:
prepare the emitter for non-debug symbols
for each non-debug symbols:
output the symbol
This way you don't need any optionals, the code is linear and straighforward to follow, the order of emitter destruction is automatically good because each emitter is in the right scope. I have uploaded the users/simark/mi-symbols-output branch on Sourceware with a commit that does that, feel free to steal from it. But the main part is:
static void
mi_symbol_info (enum search_domain kind, const char *regexp,
const char *t_regexp, bool exclude_minsyms)
{
/* Must make sure that if we're interrupted, symbols gets freed. */
global_symbol_searcher sym_search (kind, regexp, t_regexp, exclude_minsyms);
std::vector<symbol_search> symbols = sym_search.search ();
ui_out *uiout = current_uiout;
int i = 0;
ui_out_emit_tuple outer_symbols_emitter (uiout, "symbols");
/* Debug symbols are placed first. */
if (i < symbols.size () && symbols[i].msymbol.minsym == nullptr)
{
ui_out_emit_list debug_symbols_list_emitter (uiout, "debug");
/* As long as we have debug symbols... */
while (i < symbols.size () && symbols[i].msymbol.minsym == nullptr)
{
symtab *symtab = symbol_symtab (symbols[i].symbol);
ui_out_emit_tuple symtab_tuple_emitter (uiout, nullptr);
uiout->field_string ("filename", symtab_to_filename_for_display (symtab));
uiout->field_string ("fullname", symtab_to_fullname (symtab));
ui_out_emit_list symbols_list_emitter (uiout, "symbols");
/* As long as we have debug symbols from this symtab... */
while (i < symbols.size ()
&& symbols[i].msymbol.minsym == nullptr
&& symbol_symtab (symbols[i].symbol) == symtab)
{
symbol_search &s = symbols[i];
output_debug_symbol(uiout, kind, s.symbol, s.block);
i++;
}
}
}
/* Non-debug symbols are placed after. */
if (i < symbols.size ())
{
ui_out_emit_list nondebug_symbols_list_emitter (uiout, "nondebug");
/* As long as we have nondebug symbols... */
while (i < symbols.size ())
{
gdb_assert (symbols[i].msymbol.minsym != nullptr);
output_nondebug_symbol(uiout, symbols[i].msymbol);
i++;
}

+@noindent
+Return a list containing the names and types for all global variables
+taken from the debug information. The variables are grouped by source
+file, and shown with the line number on which each variable is
+defined.
+
+The @code{--include-nondebug} option causes the output to include
+data symbols from the symbol table.
+
+The options @code{--type} and @code{--name} allow the symbols returned
+to be filtered based on either the name of the variable, or the type
+of the variable.
+
+@subsubheading @value{GDBN} Command
+
+The corresponding @value{GDBN} command is @samp{info variables}.

Patch Set 7:
Simon, thanks for the awesome feedback. I've stolen your code to use as the core of the symbol printing loop. I've addressed the few other issues that remained in code that isn't deleted as a result of switching to your printing algorithm.
I think everything raised so far is now addressed in this latest version.

+@noindent
+Return a list containing the names and types for all global variables
+taken from the debug information. The variables are grouped by source
+file, and shown with the line number on which each variable is
+defined.
+
+The @code{--include-nondebug} option causes the output to include
+data symbols from the symbol table.
+
+The options @code{--type} and @code{--name} allow the symbols returned
+to be filtered based on either the name of the variable, or the type
+of the variable.
+
+@subsubheading @value{GDBN} Command
+
+The corresponding @value{GDBN} command is @samp{info variables}.
