Before, when parsing memunits, if overflow occured it failed silently.
Use nowrap u64 math to detect overflow, compare to INT64_MAX and if
greater tell user and fail accordingly.
15000000.5 TB fails double check as it a greater floating number than
(double)INT64_MAX
8388608.1 TB passes double check because it falls in the same value as
(double)INT64_MAX (which is 2^63), but will fail the int check because
(uint64_t)d, which is 2^63, is strictly greater than 2^63-1 (INT64_MAX).

Before inspecting the p_chan, we must check if the circuit is marked for close
because if it is the case, the channels are nullified from the circuit.
Several valid cases can mark the circuit for close of the directory
connection.

hs_client_purge_state() and hs_cache_clean_as_client() can remove a descriptor
from the client cache with a NEWNYM or simply when the descriptor expires.
Which means that for an INTRO circuit being established during that time, once
it opens, we lookup the descriptor to get the IP object but hey surprised, no
more descriptor.
The approach here is minimalist that is accept the race and close the circuit
since we can not continue. Before that, the circuit would stay opened and the
client wait the SockTimeout.
Fixers #28970.

Only use the HS circuit map to know if an introduction circuit is established
or not. No need for a flag to keep state of something we already have in the
circuit map. Furthermore, the circuit map gets cleaned up properly so it will
always have the "latest truth".
This commit also removes a unit test that was testing specifically that flag
but now we rely solely on the HS circuit map which is also tested few lines
below the removed test.

Our minimum version is now 0.2.9.5-alpha. Series 0.3.0, 0.3.1,
0.3.2, 0.3.3, and 0.3.4 are now rejected.
Also, extract this version-checking code into a new function, so we
can test it.
Closes ticket 31549.
Also reject 0.3.5.0 through 0.3.5.6-rc as unstable.
Make clear in the man page, in both the bandwidth section and the
accountingmax section, that Tor counts in powers of two, not
powers of ten: 1 GByte is 1024*1024*1024 bytes, not one billion
bytes.
Resolves ticket 32106.
