89f718c4c5 LookupServer: Don't cache DNS questions 
We should only cache RRs (which we represent as instances of DNSAnswer), now
which questions generated them.

80f7489df0 LookupServer: Fix serializing name data in DNS answers 
When serializing a RR of type PTR, we should use the DNS name serialization
format, not a raw string.

ae1e82fd2f LookupServer: Introduce DNSName 
This is a wrapper around a string representing a domain name (such as
"example.com"). It never has a trailing dot.

For now, this class doesn't do much except wrap the raw string. Subsequent
commits will add or move more functionality to it.

179dba652e LibGfx: Insert pixel and ttf fonts into Typeface structure 
This adds a new structure 'Typeface' to the FontDatabase that
represents all fonts of the same family and variant.
It can contain a list of BitmapFonts with varying size but of
the same family and weight or a pointer to a single TTF font
for all sizes of this Typeface.

3fe7ac0924 LibCrypto: Make a better ASN.1 parser 
And use it to parse RSA keys.
As a bonus, this one shouldn't be reading out of bounds or messing with
the stack (as much) anymore.

ca731e2cdd SystemMonitor: Define graphs by ColorRole, not by Color 
Currently, graphs are defined in terms of graph color. This means that
when the system palette is changed, the old colors are still used. We
switch to storing the color roles and looking up the palette colors on
paint events. We also define the graph line background color as the
graph color at half-transparency.

1c6fd749dc LibCrypto: memcmp() all bytes in UnsignedBigInteger::operator== 
`length` is only the (trimmed) size of the word vector, so we have to
multiply it with the size of each element to ensure all bytes are
compared.

Fixes #5335.

781d29a337 Kernel+Userland: Give sys$recvfd() an options argument for O_CLOEXEC 
@bugaevc pointed out that we shouldn't be setting this flag in
userspace, and he's right of course.

8415866c03 Kernel: Remove user/kernel flags from Region 
Now that we no longer need to support the signal trampolines being
user-accessible inside the kernel memory range, we can get rid of the
"kernel" and "user-accessible" flags on Region and simply use the
address of the region to determine whether it's kernel or user.

This also tightens the page table mapping code, since it can now set
user-accessibility based solely on the virtual address of a page.

05bb11f482 LibIPC: Make received file descriptors close-on-exec by default 
I noticed that programs running in the terminal had an open file
descriptor for the system theme buffer, inherited from the Terminal.

Let's be nice and always mark incoming fds with FD_CLOEXEC.

b671577223 HackStudio: Project templates and New Project dialog

as well as a pretty New Project dialog, inspired by early VS.NET

a6fdc17f3f LibGUI: add 'always_wrap_item_labels' property to IconView. 
In some circumstances (like template selection dialogs,) displaying as much
item label as possible, on all items, may be desired.

The default setting is 'false', which matches the default behaviour from before;
only wrapping on hover or selection.
