93dfb12037 Remember log messages that happen before logs are configured
(And replay them once we know our first real logs.)

This is an implementation for issue 6938.  It solves the problem of
early log mesages not getting sent to log files, but not the issue of
early log messages not getting sent to controllers.

1eea7a68ed Use S?SIZE_MAX, not S?SIZE_T_MAX
This fixes bug 13102 (not on any released Tor) where using the
standard SSIZE_MAX name broke mingw64, and we didn't realize.

I did this with
   perl -i -pe 's/SIZE_T_MAX/SIZE_MAX/' src/*/*.[ch] src/*/*/*.[ch]

7573e66b99 Treat Z_BUF_ERROR as TOR_ZLIB_BUF_FULL when finalizing a zlib buffer
Otherwise, when we're out of input *and* finalizing, we might report
TOR_ZLIB_OK erroneously and not finalize the buffer.

(I don't believe this can happen in practice, with our code today:
write_to_buf_zlib ensures that we are never trying to write into a
completely empty buffer, and zlib says "Z_OK" if you give it even
one byte to write into.)

Fixes bug 11824; bugfix on 0.1.1.23 (06e09cdd47).

57c48bf734 Apply the MALLOC_ZERO_WORKS fixup to tor_realloc as well.
Also, make MALLOC_ZERO_WORKS never get applied when clang analyzer is
running.  This should make the clangalyzer a little happier.

00ffccd9a6 Another clang analyzer complaint wrt HT_GENERATE
We're calling mallocfn() and reallocfn() in the HT_GENERATE macro
with the result of a product.  But that makes any sane analyzer
worry about overflow.

This patch keeps HT_GENERATE having its old semantics, since we
aren't the only project using ht.h.  Instead, define a HT_GENERATE2
that takes a reallocarrayfn.

efcab43956 Fix a number of clang analyzer false-positives
Most of these are in somewhat non-obvious code where it is probably
a good idea to initialize variables and add extra assertions anyway.

Closes 13036.  Patches from "teor".

6b9016fe3c Correct check_private_dir's dir mode
This commit attempts to satisfy nickm's comment on check_private_dir() permissions:
https://trac.torproject.org/projects/tor/ticket/11291#comment:12
"""check_private_dir() ensures that the directory has bits 0700 if CPD_CHECK_MODE_ONLY is not set. Shouldn't it also ensure that the directory has bits 0050 if CPD_CHECK_MODE_ONLY is not set, and CPD_GROUP_READ is set?"""

4144b4552b Always event_del() connection events before freeing them
Previously, we had done this only in the connection_free() case, but
when we called connection_free_() directly from
connections_free_all(), we didn't free the connections.

7c1143e11f Terser ways to sandbox-allow related filenames
Using the *_array() functions here confused coverity, and was actually
a bit longer than we needed.  Now we just use macros for the repeated
bits, so that we can mention a file and a suffix-appended version in
one line.

7c61d10c6c Fix return value of tor_fd_seekend.
Previously, we had documented it to return -1 or 0, when in fact
lseek returns -1 or the new position in the file.

This is harmless, since we were only checking for negative values
when we used tor_fd_seekend.
