Make clear that Tor's C code targets C99 standards. This makes it more
explicit what to expect for new code, because guessing from existing
code is not always reliable, especially for code that predates the
change in standard.
Per ticket #32888 this should address logging "the Address torrc
option", "and whether it is an IP address, or a DNS name"; or the
detected "local hostname", "and whether it is an IP address, or a DNS
name". Some of these details already seem to be logged, so just add
what's missing.
Resume being willing to use preemptively-built circuits when
UseEntryGuards is set to 0. We accidentally disabled this feature with
that config setting (in our fix for #24469), leading to slower load times.
Fixes bug 34303; bugfix on 0.3.3.2-alpha.
Add an inline helper function that indicates if the cached object contains a
decrypted descriptor or not.
The descriptor object is NULL if tor is unable to decrypt it (lacking client
authorization) and some actions need to be done only when we have a decrypted
object.
This improves code semantic.

The warning was:
11:23:10 ../tor/src/feature/hs/hs_service.c: In function 'log_cant_upload_desc':
11:23:10 ../tor/src/feature/hs/hs_service.c:3118:3: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
See #34254 for more info.
I guess this means that gcc assigned an unsigned type to the
`log_desc_upload_reason_t` enum and it warned if we compared it against 0...
For now I think it's simpler to remove that check instead of turning the enum
to a signed type, or trying to hack it some other way.
From what it seems, enum is up to the compiler on whether it's signed/unsigned:

Accept extra lines in nodelist and routerlist due to extra features, and
due to refactors that simplify some functions.
Most of the refactor eliminated duplicate code in smaller functions, so
there's only one large function that got smaller.
Part of 34200.
Use the node check function to check that there are enough nodes to
select a circuit path.
Adds these checks, which are implied by other code:
* supports EXTEND2 cells,
* does not allow single-hop exits,
Adds these extra checks:
* has a general-purpose routerinfo,
* if it is a direct connection, check reachable addresses.
These checks reduce the node count, but they will never under-count
nodes.
Bridge nodes aren't handled correctly, we'll fix that in the next
commit.
