9ad569c71d practracker: Add missing .may_include files 
All of these files contain "*.h", except for:
* src/app/config/.may_include
* src/test/.may_include
which also contain "*.inc".

This change prevents includes of "*.c" files, and other
unusually named files.

9395a0c765 hsv3: Remove support for client auth nicknames. 
Because the function that parses client auth credentials saved on
disk (parse_auth_file_content()) is not future compatible, there is no way to
add support for storing the nickname on the disk. Hence, nicknames cannot
persist after Tor restart making them pretty much useless.

In the future we can introduce nicknames by adding a new file format for client
auth credentials, but this was not deemed worth doing at this stage.

cbc495453c hs-v3: Give a cleanup type to hs_circ_cleanup() 
By centralizing the circuit cleanup type that is: on close, free and
repurpose, some actions on the circuit can not happen for a certain cleanup
type or for all types.

This passes a cleanup type so the HS subsystem (v2 and v3) can take actions
based on the type of cleanup.

For instance, there is slow code that we do not run on a circuit close but
rather only on free.

00136c9430 hs-v2: Move v2 circuit cleanup actions into hs_circ_cleanup() 
Refactor to decomplexify circuit_about_to_free() and finally have one single
entry point into the HS subsystems (v2 and v3) for when a circuit is freed.

With this, hs_circ_cleanup() becomes the one and only entry point when a
circuit is freed which then routes to the right subsystem version for any
actions to be taken.

This moves a big chunk of code from circuituse.c to rendclient.c. No behavior
change. Next commit will refactor it to reduce our technical debt.

In order to achieve this, the parse_extended_hostname() had to be refactored

The reason for that is so it can detect invalid onion addresses that is having

That way, we can send back the prop304 ExtendedError "X'F1' Onion Service
Descriptor Is Invalid" to notify the SOCKS connection of the invalid onion
address.

4e4c4e72d7 Handle binary IPv6 addresses and bracketed strings in RESOLVE_PTR. 
When a SOCKS5 client sends a RESOLVE_PTR request, it must include
either an IPv4 or IPv6 address.  In the past this was required to be a
binary address (address types 1 or 4), but since the refactoring of
SOCKS5 support in Tor 0.3.5.1-alpha, strings (address type 3) are also
allowed if they represent an IPv4 or IPv6 literal.

However, when a binary IPv6 address is provided,
parse_socks5_client_request converts it into a string enclosed in
brackets.  This doesn't match what string_is_valid_ipv6_address
expects, so this would fail with the error "socks5 received
RESOLVE_PTR command with hostname type. Rejecting."

By replacing string_is_valid_ipv4_address/string_is_valid_ipv6_address
with tor_addr_parse, we accept strings both with and without brackets.
This fixes the handling of binary addresses, and also improves
symmetry with CONNECT and RESOLVE requests.

Fixes bug 32315.

19cac400d9 Macros for declaring configuration structs and variable-tables 
In our old design, we had to declare configuration structures (like
or_options_t) and variable tables (like option_vars_) separately,
and we used some magic to enforce their consistency (see
conftesting.h).

With this design, we write a single definition for the configuration
object and its fields, and use C macros to expand it either into a
structure, or a variable table.  Since they are both made from the
same source, they can't become inconsistent.

The two designs can coexist happily, and we can migrate from one to
the other at our convenience.

4541a59019 lib/cc: Define the standard C macro pasting trick in one place. 
This file is a workaround for the issue that if you say `a ## b` to
create a token that is the name of a macro, the C preprocessor won't
expand that macro.  So you can't say this:

#define FOO__SQUARE(x) ((x)*(x))
#define FOO__CUBE(x)   ((x)*(x)*(x))
#define FOO(func, x)   FOO__##func(x)

Instead, the standard C trick is to add a layer of indirection:

#define PASTE(a,b)     PASTE__(a,b)
#define PASTE__(a,b)   a ## b

#define FOO__SQUARE(x) ((x)*(x))
#define FOO__CUBE(x)   ((x)*(x)*(x))
#define FOO(func, x)   PASTE(FOO__, func)(x)

We should use this kind of trick sparingly, since it gets confusing.
