this implements SHA2 (224, 256, 384, 512) signature algorithms and
uses sha256WithRSAEncryption for X509req() and X509gen() instead
of oid_md5WithRSAEncryption.

0x0D-0x11 (thanks qeed)
there are a few more device base class codes defined 0x0D-0x11, and
qemu appears to use base class code 0x00 for some of its fake
devices.

the compiler used to skip zero initialization when initializer
list was given not covering unspecified elements. now we zero
all non explicitely initialized elements. for example:
typedef struct F F;
struct F
{
int a;
int b;
int c;
};
void
main(void)
{
char a[16] = { 1, 2, 3 }; /* a[3..15] initialized to zero */
F f = { .b = 1 }; /* f.a, f.c initialized to zero */
}

the emited code that initializes local variables did not handle
unaligned data causing stack corruption, affecting code like:
void main(void)
{
char a[9] = {0};
}
this change will emit code that does byte stores for the unaligned
bytes and also handles small objects (<= 16 bytes) without branches.

tlsClient() now can optionally send the server_name in the ClientHello
message by setting the TLSconn.serverName. This is required for some
https sites.

using /proc/$pid/mem to access vga bios is not portable and crashes
sgi machines when aux/vga is run. instead, try /dev/realmodemem
first (provided by realemu), then #v/vgabios.

this allows extracting tar archives that use longnames extension,
where the real filename is stored in a special entry with
linkflag == 'L' before the file entry. also skip longlink entries
with linkflag == 'K'.

The mode printed under the -l option contains 11 characters,
interpreted as follows: the first character is
d if the entry is a directory;
a if the entry is an append-only file;
- if the entry is a plain file.
Therefore, handle them in automatically generated directory listings.

application/x-gzip bug
apache sends Content-Encoding: gzip header for Content-Type: application/x-gzip
causing hget to decompress tgz files.
from the w3c:
The Content-Encoding entity-header field is used as a modifier to the media-type.
When presented, its value indicates what additional content codings have been applied
to the entity-body, and thus what decoding mechanisms must be applied in order to
obtail the media-type referenced by the Conent-Type header field. Content-Encoding
is primarily used to allow a document to be compressed without losing the
identity of its underlying media type.
this is clearly silly, as the file is already compressed, and decompressing it
will not yield the indicated Content-type: application/x-gzip, but a tarball.
examples:

the kernel wont allow access to i/o ports 0x70/0x71, so
ignore the access. reads return 0xFF. this fixes vesa on
lenovo e540.

userspace note handlers, like any function, expect ther
first argument in R0 register on arm.
|
|
as mischief and qrstuv point out, these functions are not very usefull
and are even implemented wrong (incrementCTR()), so deleting the code.
