Thumb2 addresses are a bit a mess, depending on whether a label is
interpreted as a function pointer value (for use with BX and BLX) or as
a program counter value (for use with PC-relative addressing). Clang's
integrated assembler mis-assembles this code. See
https://crbug.com/124610#c54 for details.
Instead, use the ADR pseudo-instruction which has clear semantics and
should be supported by every assembler that handles the OpenSSL Thumb2
code. (In other files, the ADR vs SUB conditionals are based on
__thumb2__ already. For some reason, this one is based on __APPLE__, I'm
guessing to deal with an older version of clang assembler.)
It's unclear to me which of clang or binutils is "correct" or if this is
even a well-defined notion beyond "whatever binutils does". But I will
note that https://github.com/openssl/openssl/pull/4669 suggests binutils
has also changed behavior around this before.

Fixes#5405, #1381
The base64 filter BIO reads its input in chunks of B64_BLOCK_SIZE bytes.
When processing input in PEM format it can happen in rare cases that
- the trailing PEM marker crosses the boundary of a chunk, and
- the beginning of the following chunk contains valid base64 encoded data.
This happened in issue #5405, where the PEM marker was split into
"-----END CER" and "TIFICATE-----" at the end of the first chunk.
The decoding of the first chunk terminated correctly at the '-' character,
which is treated as an EOF marker, and b64_read() returned. However,
when called the second time, b64_read() read the next chunk and interpreted
the string "TIFICATE" as valid base64 encoded data, adding 6 extra bytes
'4c 81 48 08 04 c4'.
This patch restores the assignment of the error code to 'ctx->cont', which
was deleted accidentally in commit 5562cfaca4 and which prevents b64_read()
from reading additional data on subsequent calls.
This issue was observed and reported by Annie Yousar.

Since fabs(3m) is the only reference, it makes more sense to avoid it.

With this, we introduce the make variable 'libdir', which differs from
'LIBDIR' not only in casing, but also by being the absolute path to
the library installation directory. This variable is intentionally
compatible with the GNU coding standards.
When --libdir is given an absolute path, it is considered as a value
according to GNU coding standards, and the variables LIBDIR and libdir
will be this:
LIBDIR=
libdir=/absolute/path
When --libdir is given a relative path (just the name of the desired
library directory), or not given at all, it is considered as a
"traditional" OpenSSL value, and the variables LIBDIR and libdir will
be this:
LIBDIR=relativepath
libdir=$(INSTALLTOP)/$(LIBDIR)

makedepend makes lesser sense in a throw-away build like CI, but
it spares some computational time, because with MSVC it takes

When compiling with -Wall on a machine with an old compiler it gives a false
positive that the dc variable which is a structure of type DISPLAY_COLUMNS
could be used uninitialised. In fact the dc variable's members will always get
set in the case it is used, otherwise it is left uninitialised.
This fix just causes the dc variable's members to always get initialised to 0
at declaration, so the false positive will not get flagged.
