GPXE's eepro100 driver did not detect a valid link.

Hello,
There is a small incoherency in curses_keys.h, which makes it fail to
emit \n when using e.g. -k fr: curses2keysym transforms \r and 0x157
into \n, but name2keysym binds \r with Return, not \n. The patch below
fixes that.

If you make use of hw breakpoints on a 32bit x86 linux host, qemu
will segmentation fault when processing the exception.
The problem is that the value of env is stored in $ebp in the op_helper
raise_exception() function, and it can have the wrong value when
calling it from non generated code.
It is possible to work around the problem by restoring the value of
env before calling raise_exception() using a new helper function that
takes (CPUState *) as one of the arguments.

IEEE FP instructions are split up so that the rounding mode
coming from the instruction and exceptions (both masking and
delivery) are handled external to the base FP operation.
FP exceptions are properly raised for non-finite inputs to
instructions that do not indicate software completion.
A shortcut is applied if CONFIG_SOFTFLOAT_INLINE is defined
at the top of translate.c: data is loaded and stored into
FP_STATUS directly instead of using the functional interface
defined by "softfloat.h".

The CRF_{CH,CL,CH_OR_CL,CH_AND_CL} constants were all off by one bit
position. Because of this, the SPE evcmp* family of instructions would
store values in the result condition register that were also off by one
bit position.
Fixed by using the CRF_{LT,GT,EQ,SO} constants for the shift amounts.

With this patch, 'gdb detach' correctly resumes the inferior execution
after detaching the debugger.
The bug was caused by qemu asking gdb to execute a syscall (isatty)
after the detach, and then waiting (forever) for the reply. I fixed this
by properly setting gdb_syscall_mode appropriately in the 'detach'
packet handling, so subsequent syscalls are solved by qemu rather than gdb.

The existing set of IPRs is totally irrelevant to user-mode emulation.
Indeed, they most are irrelevant to implementing kernel-mode emulation,

no one will ever attempt.
